Non-contact thermometer based on ESP8266

During the COVID-19 epidemic, Indian engineer Abhijit Mukherjee designed a safe body temperature measurement solution based on ESP8266. He hopes that during the rapid spread of the epidemic, something can be done to help people prevent the spread of the virus.

We are in a special period now, and it is best for people to keep a certain safe distance when taking their body temperature. There are currently very few cost-effective non-contact thermometers on the market, so Abhijit made a non-contact infrared thermometer based on ESP8266, which can automatically measure body temperature and send the results to the cloud or Webhooks (a way to publish messages to on the Slack APP). Installing the thermometer at the office door, apartment entrance, community gate, etc. will not only quickly record the temperature, but also save time and effort. And it only costs $10-12!

Key components
Sensor: Arduino Mlx90614 non-contact infrared temperature sensor module, 3-5V
Microcontroller: Nodemcu ESP8266 Wi-Fi IoT development board
LCD: 16x2 alphanumeric display
Slack messaging APP

uses this device to measure temperature, the optimal distance is 3 cm from forehead or hand. After the measurement is completed, the temperature data is sent to the operator's display. Slack APP provides an API that can be used to send alerts or notifications under specific conditions. When a body temperature higher than 37°C is detected, the system operator will be notified in time so that necessary preventive measures can be taken in a timely manner.
