Use of the MLX90614 thermometer in SMBus configuration

The key feature of MLX90614 is that it is a contactless IR temperature sensor with high accuracy. Therefore, it can be used in industries to measure the temperature of moving objects like a rotating motor shaft. With its high accuracy and precision, it is also used in a wide range of commercial, health care, and household applications like room temperature monitoring, body temperature measurement, etc.

The MLX90614 Temperature sensor is manufactured by a company called Melexis. The sensor is factory calibrated and hence it acts like a plug and play sensor module for speeding up development processes.

The MLX90614 is available in the standard TO-39 package making it easy to mount on a breadboard. The dimensions of MLX90614 is shown below.
