Getting started with MLX90614 Module with Arduino UNO
In this tutorial we are going to interface MLX90614 Module with arduino UNO so that we can print the Object temperature and Ambient temperature of the place, so before getting started as the description of Module states this module use the infrared theory to measure the temperature of the board in front of it. which means that there is no contact between the object and the module that’s why it also a contact less thermometer, so let’s get started

Step1: Hardware required
Arduino UNO
MLX90614 Module
Jumper wires
Step2: Connecting the hardware
You can choose to connect sensor I²C pin to arduino SCL, SDA or arduino pin A4,A5 they have the same function. Make sure use 3.3V for 3.3V module type. Because it will damage if connected to 5V.
