Introduction

Keyestudio MLX90614 non-contact infrared temperature sensor is mainly composed of sensor MLX90614. MLX90614 is an infrared non-contact thermometer, and the TO-39 package integrates infrared induction thermoelectric pile detector chip (MLX81101) and signal processing dedicated integrated chip MLX90302. Due to the integration of low noise amplifier, 17-bit analog digital converter and DSP processing unit, the sensor achieves high precision and high resolution measurement.

Sample Code

/*************************************************** 
  This is a library example for the MLX90614 Temp Sensor

  Designed specifically to work with the MLX90614 sensors in the
  adafruit shop
  ----> https://www.adafruit.com/products/1748
  ----> https://www.adafruit.com/products/1749

  These sensors use I2C to communicate, 2 pins are required to  
  interface
