Grove - Infrared Temperature Sensor Array(AMG8833) The Grove - Infrared Temperature Sensor Array (AMG8833) is a high precision infrared array sensor which based on advanced MEMS technology. It can support temperature detection of two-dimensional area: 8 × 8 (64 pixels) and maximum 7 meters detection distance. We provide both Arduino and Raspberry Pi demo for this sensor. It will be a perfect module to make your own thermal camera. Features • Temperature detection of two-dimensional area: 8 × 8 (64 pixels) • I2C output (capability of temperature value output) • High precision • Long detection distance Specification Item Value Operating Voltage 3.3V / 5V Temperature range of measuring object 0 °C to 80 °C +32 °F to +176 °F Operating temperature range 0 °C to 80 °C +32 °F to +176 °F Storage temperature range −20 °C to 80 °C –4 °F to +176 °F Temperature accuracy Typical ±2.5 °C ±4.5 °F Viewing angle Typical 60 ° Optical axis gap Within Typical ±5.6 ° Number of pixel 64 (Vertical 8 × Horizontal 8 Matrix) External interface I2C I2C Address 0x68(default) \ 0x69(optional) Typical Applications • High function home appliances (microwaves and air-conditioners) • Energy saving at office (air-conditioning/lighting control) • Digital signage • Automatic doors/elevators Hardware Overview Pin Out Schemaitc Power The typical voltage of AMG8833 is 3.3V, so we use the XC6206P33 chip to provide a stable 3.3V. The input of XC6206P33 ranges from 1.8V to 6.0V, so you can use this module with your Arduino both in 3.3V and 5V. Bi-directional level shifter circuit This is a typical Bi-directional level shifter circuit to connect two different voltage section of an I2C bus. The I2C bus of this sensor use 3.3V, if the I2C bus of the Arduino use 5V, this circuit will be needed. In the schematic above, Q6 and Q5 are N-Channel MOSFET 2N7002A, which act as a bidirectional switch. In order to better understand this part, you can refer to the AN10441 Platforms Supported Arduino Raspberry Pi BeagleBone Wio LinkIt ONE Caution The platforms mentioned above as supported is/are an indication of the module's software or theoritical compatibility. We only provide software library or code examples for Arduino platform in most cases. It is not possible to provide software library / demo code for all possible MCU platforms. Hence, users have to write their own software library. Getting Started Play With Arduino Hardware Materials required Seeeduino V4.2 Base Shield Infrared Temperature Sensor 2.8 TFT Touch Shield V2.0 Array Note 1 Please plug the USB cable gently, otherwise you may damage the port. Please use the USB cable with 4 wires inside, the 2 wires cable can't transfer data. If you are not sure about the wire you have, you can click here to buy 2 Each Grove module comes with a Grove cable when you buy. In case you lose the Grove cable, you can click here to buy. • Step 1. Connect the Grove - Infrared Temperature Sensor Array (AMG8833) to port I2C of Grove-Base Shield. • Step 2. Plug Grove - Base Shield into Seeeduino. • Step 3. Plug 2.8 TFT Touch Shield V2.0 into the Grove - Base Shield. • Step 4. Connect Seeeduino to PC via a USB cable. Note If we don't have Grove Base Shield, We also can directly connect this module to Seeeduino as below.

Download the Seeed_AMG8833 Library from Github. • Step 2. Refer to How to install library to install library for Arduino. • Step 3. Restart the Arduino IDE. Open the example, you can open it in the following three ways： a. Open it directly in the Arduino IDE via the path: File → Examples → Grove IR Matrix Temperature sensor AMG8833 → TFT_screen_demo. b. Open it in your computer by click the TFT_screen_demo.ino which you can find in the folder XXXXArduino\libraries\Seeed_AMG8833master\examples\TFT_screen_demo, XXXX is the location you installed the Arduino IDE. c. Or, you can just click the icon in upper right corner of the code block to copy the following code into a new sketch in the Arduino IDE. #include 1#include #include 2 #include 3 "Seeed_AMG8833_driver.h" 4AMG8833 sensor; 5#define TFT_PIXELS_NUM 30 6void parse_int_status(u8* status) { u8 val=0; 7 8 for(u32 i=0;i
