How To Make DIY Non-Contact Thermometer

Introduction

In today’s world, it’s smart to have a thermometer on hand at all times, especially during times of pandemic. Temperature measurements are often used to indicate whether someone has a fever or not, which is often a sign of illness. Non-contact thermometers, which can measure a person’s temperature without physically touching them, have become a popular choice due to COVID-19 prevention measures. In this article, we will discuss how to make a DIY non-contact thermometer.

Explanation of DIY Non-Contact Thermometer

Steps to Make a DIY Non-Contact Thermometer:

Step 1: Wiring up the MLX90614ESF-DCI IR Sensor with Arduino UNO microcontroller and LCD Display using the breadboard or PCB.

Step 2: Uploading the code to the Arduino UNO microcontroller. Link of all related code files are provided above for download.

Step 3: Powering up the DIY thermometer using the Arduino microcontroller and testing the device by hovering your hand in front of the sensor to get your temperature reading.

Conclusion:

While a non-contact thermometer can be quite costly, making a non-contact thermometer from scratch can be a great alternative. With the right materials and a bit of technical knowledge, you can create a non-contact thermometer that works just as effectively as a store-bought thermometer. This DIY project is not only cost-effective but also a great way to build your technical skills while creating a useful tool for your home. Stay safe and stay healthy.
