Introduction

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.

FAQ

What is the maximum distance for accurate temperature measurement?

The sensor can accurately measure temperature up to a few centimeters, depending on the size and emissivity of the object.

Can the sensor measure the temperature of liquids?

Yes, it can measure the surface temperature of liquids, provided the liquid surface is stable and not reflective.

Is the sensor suitable for outdoor use?

The sensor operates in a wide temperature range but should be protected from direct exposure to harsh environmental conditions like rain or dust.

How do I calibrate the sensor?

The MLX90614 comes pre-calibrated from the factory. For recalibration, specialized equipment and software are required.

Can I use this sensor with other microcontroller platforms?

Yes, it is compatible with any microcontroller that supports I2C communication, including Arduino, Raspberry Pi, and ESP32.
