Living through this pandemic has made contactless temperature sensing a must! The NCIR 2 Thermometer Unit utilizes the MLX90614 temperature sensor, and take ambient and object temperature readings with No Contact. Great for socially-distant reality.
The MLX90614 sensor is factory calibrated in wide temperature range, -40 to 125 ˚C for the ambient temperature and -70 to 380 ˚C for the object temperature. The embedded MCU - STM32 can process the data to achieve high/low temperature alert function. There are also buzzer, RGB LED, function button and reset button on board.
This Unit can either work with M5Core through I2C protocol, or work alone. Suitable for medical, environmental monitoring and home automation applications.

This was a nice improvement over the NCIR thermometer with the additional buzzer, RGB and button, however the wide Field Of View range (90°?) forces that the object measured needs to be very close to the thermometer (impractical in certain applications). For example if I put my hand or forehead, I only get an accurate reading if it is 20 cm or less, beyond that distance, the temperature reading is not useful for my project. You might consider to offer a version that instead of using the MLX90614ESF-BAA use a MLX90614ESF-DCL. This last one has a Field Of View of only 5° allowing to increase significantly the distance to measure the temperature of objects (I tried and 60 cm without any issue), for sure is more expensive, but I need these larger sensing distances. For some other projects where you can have the sensor closer to what you want to meassure it is a great choice.
I really hoped I would be able to get this to integrate into home assistant over I2C using ESP Home and an Atom Lite as I had success with a stand alone MLX90614 previously (but wanted the build quality and grove connection of m5 stack (which is AMAZING) but it wouldn't work and I couldn't find anyone else who had done it. I bought the NCIR MLX90614 and that worked perfectly. So if you're wanting this for Home Assistant, get the NCIR not the NCIR 2.
