M5Stack NCIR MLX90614 Temperature Sensor Unit

The NCIR Unit from M5Stack measures temperatures without contact using the MLX90614 infrared sensor. It detects the infrared radiation of an object and calculates the surface temperature from it, as an average over a 90° field of view. The Unit connects to Port A (I2C) with address 0x5A.

The M5Stack Unit NCIR 2 Temperature Sensor MLX90614 also has a microcontroller with alarm function, RGB LED and buzzer.
