# M5Unit - THERMO

## Overview

Library for THERMO using [M5UnitUnified](https://github.com/m5stack/M5UnitUnified).  
M5UnitUnified is a library for unified handling of various M5 units products.

### SKU:U028
NCIR featured with built-in infrared MLX90614 sensor, It can be used to measure the surface temperature of a human body or other object.

Unlike most temperature sensors, this sensor measures infrared light bouncing off of remote objects so it can sense temperature without having to touch them physically.

### SKU:U150
Unit NCIR2 is a non-contact infrared single-point temperature measurement unit equipped with a data processing MCU (STM32). It features a temperature measurement range of -70°C to 380°C, with functions such as high/low temperature alarms, RGB LED indicator, and a built-in buzzer.

### SKU:U149
Unit Thermal2 is a thermal imaging acquisition unit equipped with a data processing MCU. It features an MLX90640 thermal imaging sensor with an imaging resolution of 32 x 24 pixels, a field of view of 110° x 75°, and a temperature measurement range of -40°C to 300°C. The MCU adopts an ESP32, enabling functions such as high/low temperature alarms, average/maximum/minimum value reading, and data caching through data processing.
