In this video we learn how to build a very usefull project. An Infrared thermometer, using the MLX90614 IR temperature sensor and the a Nokia 5110 LCD display shield. We are also using an Arduino Uno but you can use any Arduino board you like.

Is it possible to use the temperature sensor to trigger a timer?
It is possible, but you will have to modify the original code as it doesn’t have this functionality.
