MLX90614 Non-Contact Infrared Temperature Sensor

Note: The MLX90614 Non-Contact Infrared Temperature Sensor comes with pre-soldered header pins starting from March 2021.

The MLX90614 is an infrared thermometer for non-contact temperature measurements. Both the IR sensitive thermopile detector chip and the signal conditioning ASIC are integrated in the same TO-39 can. Integrated into the MLX90614 are a low noise amplifier, 17-bit ADC and powerful DSP unit thus achieving high accuracy and resolution of the thermometer. This is the breakout board for MLX90614.

Here is an example of how to use contactless temperature sensor MLX90614 with an Arduino by Miliohm:
