Feature:    1. TEMPERATURE VIEW: The module contains a single chip microcomputer, the serial port directly outputs 768 temperature data, and the USB to TTL is directly transferred to the computer to view the data. 2. I2C INTERFACE: This simple thermal imager retains the original I2C interface of MLX90640, and the sensor chip can be directly operated by an external MCU (PS is connected to GND). 3. SENSOR VIEW ANGLE: The field of view angle of the imager sensor probe is 35° x 55°, the small angle design is suitable for long distance measurement, with a wider range of applications. 4. LCD DISPLAY DATA: The imager has a 2.4in 320 x 240 LCD screen that can display maximum temperature, minimum temperature, center point temperature and each coordinate point. 5. USB INTERFACE: With a USB data transmission interface, the system can be upgraded later, and the internal system can be updated for free. The default system version is 1.0. 6. SCREEN COLOR: Using the screen color corresponding to the temperature adjustment function, you can set the temperature to display different colors for easy observation. 7. WIDE APPLICATION: Can be used for various temperature detection, such as heat detection of PCB components, auto parts, electrical switches, microwave oven detection, etc. Specification: Item Type: IR Infrared Imager Sensor Resolution: 24 x 32 dot array Battery: 1000mA lithium battery (built in battery) Interface: Micro USB interface, the voltage does not exceed 5V, rechargeable Response Frequency: 8HZ Target Temperature Measurement Range: -40-300& 8451; Ambient Temperature: 0-50& 8451; Emissivity: 0.01-1.00 range adjustment Sensor Probe Field of View: Default 35° x 55° Screen: 2.4in LCD, 320 x 240 resolution, display the highest temperature, the lowest temperature, the center point temperature and the coordinate points Measurement Accuracy: ±2& 8451; (Test Conditions: Ambient 25& 8451;, Test Target: Boiling water 100& 8451;, Distance: Approx. 30mm / 1.2in) Size: Approx. 80 x 50 x 26mm / 3.1 x 2 x 1in Functions:  1. With screenshot function, you can pause the picture for analysis 2. With screen color corresponding temperature adjustment function, you can set the temperature to display different colors 3. With USB data transmission interface, the system can be upgraded later, the internal system can be updated free of charge, the default system version 1.0 4. With USB data transmission interface, the new firmware version automatically outputs data to the USB port by default, and can directly connect to computer software to display images at the same time (computer software baud rate 115200, 8HZ), or use the corresponding serial port assistant to save image data on the computer Application: Human body temperature detection, PCB component fever detection temperature, floor heating temperature detection, auto parts temperature detection, electrical switch temperature detection, conditioning microwave oven detection, etc.
