The IR Infrared 3-Wire Flame Detection Sensor Module is a compact fire and flame detection sensor designed for Arduino, ESP32, Raspberry Pi, and other microcontroller projects. The module uses an infrared photodiode to detect flame or fire sources within the 760nm to 1100nm wavelength range, making it highly sensitive to candle flames, lighters, and open fires.
The module provides a digital output signal and includes an onboard LM393 comparator for stable and accurate flame detection. Sensitivity can be adjusted easily using the onboard potentiometer, allowing you to fine-tune the detection distance and trigger point for your project.
