Non-contact forehead thermometer program

Non-contact forehead temperature gun solution compatible with universal male models and various infrared sensors

PCB assembly estimated cost: 150 CNY

 An Introduction

Provide software, hardware, technical support and services including PCBA.

 application solution

The main control circuit of non-contact thermometer is divided into two types: analog circuit and digital circuit. The processing method of analog circuit cannot be guaranteed. It is generally used in industrial measurement. Digital circuit improves the A / D converter by amplifying the signal. Resolution and accuracy can reach ± 0.1 ℃, which is more suitable for the measurement of human temperature.

Structure

Application

Measure body temperature based on the infrared radiation energy emitted by the human body

Features

Compatible with general-purpose male models and infrared sensors. The final module is grounded and supported by the Huaqiu development team. This module supports and is compatible with current general-purpose sensor solutions.
