SKU:DFR0588 (https://www.dfrobot.com/forum/) (https://www.dfrobot.com/) Introduction Gravity: Analog SHT30 Temperature & Humidity Sensor adopts the new generation SHT30 temperature and humidity sensor from Sensirion. Thanks to Sensirion's CMOSens® technology, highly integrated capacitive humidity sensing components and bandgap temperature sensing components, the SHT30 offers high reliability and long-term stability with low power consumption, fast response and immunity to interference. The sensor is internally calibrated, linearized and amplified to output analog voltages that are linear with temperature or humidity. It is compatible with 3.3V/5V controllers such as Arduino, micro:bit, ESP32. It is easy to achieve precise and high reliability temperature and humidity sensing for urban environment monitoring, intelligent buildings, industrial automation, smart home and other Internet of Things applications. Features Internal auto calibration, linear analog voltage output High precision, low power consumption, fast response Compatible with 3.3V/5V controller Application Urban Environmental Monitoring Intelligent Building, Home Industrial Automation Specification IC (Sensor): Sensirion SHT30 Input Voltage (VCC) : 3.3V - 5.5V Interface: Gravity Analog (PH2.0-3P，analog voltage output 0.3-2.7V) Quiescent Current: 2s Humidity Performance Range: 0 - 100 %RH Resolution: 0.006 %, 14bit Accuracy: ±3 %RH@10 - 90 %RH (typical)，±8 %RH@0 - 100 %RH (typical) Response Time: >8s Response Time: >8s Board Overview No. Label Description 1 - Power GND 2 + Power VCC（3.3~5.5V） 3 RH Relative humidity analog output (0.3-2.7V) 4 T Temperature analog output (0.3-2.7V) 5 / 2.54mm-4P via pinout Output Characteristic When the module is powered within rated input voltage and works normally, it outputs a lt f 0 3 2 7V hi h i li ith t t h idit Th di voltage of 0.3~2.7V which is linear with temperature or humidity.
