IR Flame Sensor Module 4 Pin

This 4-pin IR Flame Sensor Module is a highly sensitive and versatile tool for detecting fire and flames. It is designed to sense infrared light with a wavelength between 760nm and 1100nm, which is characteristic of a flame source. The module features dual outputs: a digital output (DO) for a simple high/low signal and an analog output (AO) that provides a voltage proportional to the flame’s intensity. With an onboard potentiometer, you can easily adjust the sensitivity to suit your project’s specific needs. Its wide detection angle and compatibility with microcontrollers like Arduino and Raspberry Pi make it an ideal component for building fire alarm systems, fire-fighting robots, and other safety-critical applications.
