Bloga Schematic of the experimental setup for contactless thermography Circuit Diagram Verify temperature readings: Compare the temperature readings from the contactless thermometer with a known reference, such as a calibrated mercury thermometer or a high-quality digital thermometer. If the readings differ significantly, calibrate the MLX90614 sensor as described in the "Calibrating the Thermometer" section. This simple Arduino project can be used to monitor your own temperature every morning or used in public places as contact less thermometer.

Contactless Smart IR Thermometer using Arduino and Android Circuit Diagram
If your sensor is not on breakout board gonna need to pull-up the SDA and SCL pins of it, the put a capacitor between the GND and +3.3v pins. If its on breakout board then just connect the pins to the Arduino board, SDA with A5 and SCL with A4, GND to GND and +3.3 to 3.3v. To operate the IR thermometer, you need to continuously press the longest button (the one we soldered to pin D5 of the arduino), bring the thermometer close to an obstacle and when the thermometer is close enough, it will beep and take the temperature. You can change the mode (medical or object) by pressing the other button for about 3s.
In the above prototype circuit of a contactless IR thermometer circuit, we find the thermopile sensor IC MLX90247 in the bipolar mode, configured with an external op amp designed to amplify tiny electrical from the thermopile into a measurable output. A simple differential VU meter is attached across the outputs of the two op amps. As long

3D Printed Enclosure for Contactless IR Thermometer. The idea of the project is to make the thermometer compact enough to mount it along with our phone. We designed a CAD model to fit all the electronics into a neat little box used paper clip to secure the device with the phone. The CAD model is shown below.
