Humidity response time in the application depends on the design-in of the sensor. 5 Response time is measured when the sensor is exchanged between water reservoirs of different temperatures 1 www.sensirion.com Version 1.0 – September 2018 2/15 2.1 Recommended Operating Conditions The sensor shows best performance when operated within recommended normal temperature and humidity range of 5 °C – 60 °C and 20 %RH – 80 %RH, respectively. Long-term exposure to conditions outside normal range, especially at high humidity, may temporarily offset the RH signal (e.g. +3%RH after 60h kept at >80%RH). After returning into the normal temperature and humidity range the sensor will slowly come back to calibration state by itself. Prolonged exposure to extreme conditions may accelerate ageing. 3 3.1 Electrical Specifications Electrical Characteristics Parameter Supply voltage Power-up/down level Symbol VDD VPOR Slew rate change of the supply voltage VDD,slew Supply current Condition Min. 2.4 1.8 Typ. 3.3 2.1 Max. 5.5 2.4 - - 20 idle state (single shot mode) 0.2 2.0 idle state (periodic data acquisition mode) - 45 - Measuring - 800 1500 2 - IDD - Average Units Comments V V Voltage changes on the VDD line between VDD,min and VDD,max V/ms should be slower than the maximum slew rate; faster slew rates may lead to reset; Current when sensor is not performing a µA measurement during single shot mode Current when sensor is not performing a µA measurement during periodic data acquisition mode Current consumption µA while sensor is measuring Current consumption (operation with one measurement per µA second at lowest repeatability, single shot mode) Table 3 Electrical specifications, values measured at 25°C. www.sensirion.com Version 1.0 – September 2018 3/15 3.2 Timing Specifications Parameter Symbol Conditions Min.

Low frequencies (below 100 kHz) are recommended for applications where the module is connected by a cable because of capacitive coupling of cables with the I2C bus. For detailed information on the I2C protocol, refer to NXP I2C-bus specification7. After sending a command to the sensor a minimal waiting time of 1ms is needed before another command can be received by the sensor. Furthermore, to keep self-heating below 0.1°C, the SCC30-DB should not be active for more than 10% of the time. All SCC30-DB commands and data are mapped to a 16-bit address space. Additionally, data and commands are protected with a CRC checksum. This increases communication reliability. The 16 bits commands to the sensor already include a 3 bit CRC checksum. Data sent from and received by the sensor is always succeeded by an 8 bit CRC. In write direction it is mandatory to transmit the checksum, since the SCC30-DB only accepts data if it is followed by the correct checksum. In read direction it is left to the master to read and process the checksum. 5.1 I2C Address The I2C device address is given Table 6: SCC30-DB Hex. Code Bin. Code 2 I C address 0x44 100’0100 Table 6 SCC30-DB I2C device address. Each transmission sequence begins with START condition (S) and ends with an (optional) STOP condition (P) as described in the I2C-bus specification. 5.2 Power-Up and Communication Start The sensor starts powering-up after reaching the power-up threshold voltage VPOR specified in Table 3. After reaching this threshold voltage the sensor needs the time tPU to enter idle state. Once the idle state is entered it is ready to receive commands from the master (microcontroller). Each transmission sequence begins with a START condition (S) and ends with a STOP condition (P) as described in the I2Cbus specification. Whenever the sensor is powered up, but not performing a measurement or communicating, it automatically enters idle state for energy saving. This idle state cannot be controlled by the user. 5.3 Starting a Measurement A measurement communication sequence consists of a START condition, the I2C write header (7-bit I2C device address plus 0 as the write bit) and a 16-bit measurement command. The proper reception of each byte is indicated by the sensor. It pulls the SDA pin low (ACK bit) after the falling edge of the 8th SCL clock to indicate the reception. A complete measurement cycle is depicted in Table 7. With the acknowledgement of the measurement command, the SCC30-DB starts measuring humidity and temperature. 7 http://www.nxp.com/documents/user_manual/UM10204.pdf www.sensirion.com Version 1.0 – September 2018 5/15 5.4 Measurement Commands for Single Shot Data Acquisition Mode In this mode one issued measurement command triggers the acquisition of one data pair. Each data pair consists of one 16-bit temperature and one 16-bit humidity value (in this order). During transmission each data value is always followed by a CRC checksum, see Section 5.5. In single shot mode different measurement commands can be selected. The 16-bit commands are shown in Table 7. They differ with respect to repeatability (low, medium and high). The repeatability setting influences the measurement duration and thus the overall energy consumption of the sensor. This is explained in Section 3. Command MSB I2C write header P 16-bit command I2C Address P S I2C Address R I2C read header Temperature LSB Humidity LSB 16-bit humidity value Checksum ACK Humidity MSB ACK 16-bit temperature value CRC ACK ACK measurement completed CRC NACK SCL free Temperature MSB R I2C read header ACK S measurement ongoing: no read header for 1ms measurement ongoing Command LSB ACK SCL free LSB 00 0B 16 ACK W ACK I2C Address NACK S ACK Condition Hex. code Repeatability MSB High Medium 0x24 Low e.g. 0x2400: high repeatability measurement. P Checksum Table 7 Measurement commands in single shot mode. The first “SCL free” block indicates a minimal waiting time of 1ms. (Clear blocks are controlled by the microcontroller, grey blocks by the sensor). 5.5 Readout of Measurement Results for Single Shot Mode After the sensor has completed the measurement, the master can read the measurement results (pair of RH & T) by sending a START condition followed by an I2C read header. The sensor responds to a read header with a not acknowledge (NACK), if the measurement is still ongoing and thus no data is present. If the measurement is completed, the sensor will acknowledge the reception of the read header and send two bytes of data (temperature) followed by one byte CRC checksum and another two bytes of data (relative humidity) followed by one byte CRC checksum. Each byte must be acknowledged by the microcontroller with an ACK condition for the sensor to continue sending data. If the sensor does not receive an ACK from the master after any byte of data, it will not continue sending data. The sensor will send the temperature value first and then the relative humidity value. After having received the checksum for the humidity value a NACK and stop condition should be sent (see Table 7). The I2C master can abort the read transfer with a NACK condition after any data byte if it is not interested in subsequent data, e.g. the CRC byte or the second measurement result, in order to save time. In case the user needs humidity and temperature data but does not want to process CRC data, it is recommended to read the two temperature bytes of data with the CRC byte (without processing the CRC data); after having read the two humidity bytes, the read transfer can be aborted with a with a NACK. www.sensirion.com Version 1.0 – September 2018 6/15 5.6 Measurement Commands for Periodic Data Acquisition Mode In this mode one issued measurement command yields a stream of data pairs. Each data pair consists of one 16-bit temperature and one 16-bit humidity value (in this order). In periodic mode different measurement commands can be selected. The corresponding 16-bit commands are shown in Table 8. They differ with respect to repeatability (low, medium and high) and data acquisition frequency (0.5, 1, 2, 4 & 10 measurements per second, mps). The data acquisition frequency and the repeatability setting influences the measurement duration and the current consumption of the sensor. This is explained in Section 3 of this datasheet. If a measurement command is issued, while the sensor is busy with a measurement (measurement durations see Table 4), it is recommended to issue a break command first (see Section 5.9). Upon reception of the break command the sensor will abort the ongoing measurement and enter the single shot mode. Condition Hex. code Repeatability mps MSB LSB High 32 Medium 0.5 0x20 24 Low 2F High 30 Medium 1 0x21 26 Low 2D High 36 Medium 2 0x22 20 Low 2B High 34 Medium 4 0x23 22 Low 29 High 37 Medium 10 0x27 21 Low 2A e.g. 0x2130: 1 high repeatability mps - measurement per second 4 5 6 I2C write header 7 8 9 W 1 2 3 4 5 6 7 Command MSB 8 9 10 11 12 13 14 15 16 17 18 Command LSB ACK 3 ACK 2 I2C Address ACK 1 S 16-bit command Table 8 Measurement commands for periodic data acquisition mode (Clear blocks are controlled by the microcontroller, grey blocks by the sensor). N.B.: At the highest mps setting self-heating of the sensor might occur. 5.7 Readout of Measurement Results for Periodic Mode Transmission of the measurement data can be initiated through the fetch data command shown in Table 9. If no measurement data is present the I2C read header is responded with a NACK (Bit 9 in Table 9) and the communication stops. After the read out command fetch data has been issued, the data memory is cleared, i.e. no measurement data is present. www.sensirion.com Version 1.0 – September 2018 7/15 Command Hex code Fetch Data 0x E0 00 Table 9 Fetch Data command (Clear blocks are controlled by the microcontroller, grey blocks by the sensor). 5.8 ART Command The ART (accelerated response time) feature can be activated by issuing the command in Table 10. After issuing the ART command the sensor will start acquiring data with a frequency of 4Hz. The ART command is structurally similar to any other command in Table 8. Hence Section 5.6 applies for starting a measurement, Section 5.7 for reading out data and Section 5.9 for stopping the periodic data acquisition. The ART feature can also be evaluated using the Evaluation Kit EK-H5 from Sensirion. Command Hex Code Periodic Measurement with ART 0x2B32 4 5 6 7 8 9 W I2C write header 1 2 3 4 5 6 7 Command MSB 8 9 10 11 12 13 14 15 16 17 18 Command LSB ACK 3 ACK 2 I2C Address ACK 1 S 16-bit command Table 10 Command for a periodic data acquisition with the ART feature (Clear blocks are controlled by the microcontroller, grey blocks by the sensor). 5.9 Break Command / Stop Periodic Data Acquisition Mode The periodic data acquisition mode can be stopped using the break command shown in Table 11. It is recommended to stop the periodic data acquisition prior to sending another command (except Fetch Data command) using the break command. Upon reception of the break command the sensor will abort the ongoing measurement and enter the single shot mode. This takes 1ms. Command Hex Code Break 0x3093 Table 11 Break command (Clear blocks are controlled by the microcontroller, grey blocks by the sensor). 5.10 Reset A system reset of the SCC30-DB can be generated externally by issuing a command (soft reset). Additionally, a system reset is generated internally during power-up. During the reset procedure the sensor will not process commands. www.sensirion.com Version 1.0 – September 2018 8/15 Interface Reset If communication with the device is lost, the following signal sequence will reset the serial interface: While leaving SDA high, toggle SCL nine or more times. This must be followed by a Transmission Start sequence preceding the next command. This sequence resets the interface only. The status register preserves its content. Soft Reset / Re-Initialization The SCC30-DB provides a soft reset mechanism that forces the system into a well-defined state without removing the power supply. When the system is in idle state the soft reset command can be sent to the SCC30-DB. This triggers the sensor to reset its system controller and reloads calibration data from the memory. In order to start the soft reset procedure the command as shown in Table 12 should be sent. It is worth noting that the sensor reloads calibration data prior to every measurement by default. Command Hex Code Soft Reset 0x30A2 Table 12 Soft reset command (Clear blocks are controlled by the microcontroller, grey blocks by the sensor). Reset through General Call Additionally, a reset of the sensor can also be generated using the “general call” mode according to I2C-bus specification7. It is important to understand that a reset generated in this way is not device specific. All devices on the same I2C bus that support the general call mode will perform a reset. Additionally, this command only works when the sensor is able to process I2C commands. The appropriate command consists of two bytes and is shown in Table 13. Command Code Address byte Second byte Reset command using the general call address 0x00 0x06 3 4 5 6 7 0x0006 8 S General Call Address st General Call 1 byte 9 1 2 3 4 5 6 7 Reset Command 8 9 ACK 2 ACK 1 General Call 2nd byte Table 13 Reset through the general call address (Clear blocks are controlled by the microcontroller, grey blocks by the sensor). Hard Reset A hard reset is achieved by switching the supply voltage to the VDD Pin off and then on again. In order to prevent powering the sensor over the ESD diodes, the voltage to pins 1 (SCL) and 4 (SDA) also needs to be removed. 5.11 Heater The SHT3x sensor on the SCC30-DB is equipped with an internal heater, which is meant for plausibility checking only. The temperature increase achieved by the heater depends on various parameters and lies in the range of a few degrees centigrade. It can be switched on and off by command, see table below. The status is listed in the status register. After a reset the heater is disabled (default condition). www.sensirion.com Version 1.0 – September 2018 9/15 Command Heater Enable Heater Disabled Hex Code MSB LSB 0x30 6D 66 Table 14 Heater command (Clear blocks are controlled by the microcontroller, grey blocks by the sensor). 5.12 Status Register The status register contains information on the operational status of the heater, the alert mode and on the execution status of the last command and the last write sequence. The command to read out the status register is shown in Table 15 whereas a description of the content can be found in Table 16.

Command Hex Code Clear status register 0x 30 41 Table 17 Command to clear the status register (Clear blocks are controlled by the microcontroller, grey blocks by the Sensor) 5.13 Checksum Calculation The 8-bit CRC checksum transmitted after each data word is generated by a CRC algorithm. Its properties are displayed in Table 18. The CRC covers the contents of the two previously transmitted data bytes. To calculate the checksum only these two previously transmitted data bytes are used. Property Name Width Protected data Polynomial Initialization Reflect input Reflect output Final XOR Examples Value CRC-8 8 bit read and/or write data 0x31 (x8 + x5 + x4 + 1) 0xFF False False 0x00 CRC (0xBEEF) = 0x92 Table 18 I2C CRC properties. 5.14 Conversion of Signal Output Measurement data is always transferred as 16-bit values (unsigned integer). These values are already linearized and compensated for temperature and supply voltage effects. Converting those raw values into a physical scale can be achieved using the following formulas.
