Build Your Own Portable Contactless Temperature Reader

Introduction

Covid-19 have been declared as pandemic. One of the early symptoms of corona virus was fever, and we are advised to reduce the direct contact. So, I try to develop a portable contactless temperature reader using ESP32 and Arduino platform. Later, you can improve the code to implement IoT in the application.

Before proceed to the tutorial, please go through following tutorial first on how to install and edit the library.

• Interface LSM9DS1 9DOF IMU With TTGO T-Display ESP32 – Install TFT_eSPI library and edit.
• Send Sensor Data to Adafruit IO Using ESP32 – Install MLX90614 library.

Video

This video shows how to build your own Portable Contactless Temperature Reader using Arduino platform.

Hardware Preparation

This is the list of items used in the video.

If you have Snapmaker or Ender3, you can access 👉 TinkerCAD 3D file,
export to .stl and print your casing.

Sample Program

This is Arduino sample program for ESP32 board. Before compile, please install following libraries through Library Manager:

• TFT_eSPI by Bodmer Version 1.4.20
• MLX90614 Library by Adafruit Version 1.0.1

Thank You
