MLX90614 Contactless Infrared Temperature Sensor

The MLX90614 is a high-precision, non-contact infrared (IR) thermometer designed for sensing the temperature of an object from a distance. By measuring the IR light bouncing off an object, it can calculate the temperature without physical touch. This makes it ideal for medical thermometers, industrial moving parts, or livestock monitoring. The module features an internal 17-bit ADC and a powerful Digital Signal Processor (DSP) to ensure high accuracy and resolution.
