Basic structure of infrared thermometer

Infrared thermometer is used to measure body temperature by infrared, which can be divided into contact type and non-contact type. Infrared thermometer temperature measurement, relatively safe and accurate, suitable for the elderly, children, hospitals and families.

Infrared thermometer AXD-515 is a kind of thermometer which uses the radiation principle to measure the body temperature. Its infrared sensor absorbs the infrared radiation of the human body and senses the body temperature.The infrared radiation of human body is focused on the detector, which converts the radiation power into electrical signal, which can be displayed in centigrade (or Fahrenheit) after being compensated for the ambient temperature.

Basic structure:

1. Contact infrared thermometer. Taking the ear thermometer as an example, it is mainly composed of shell, temperature probe, temperature sensor, PCB circuit, LCD, buzzer and battery.

2. Non contact infrared thermometer. Taking the forehead temperature gun as an example, it is mainly composed of infrared probe assembly, main circuit board assembly, LCD display assembly, shell assembly, buzzer and battery.
