Fire/Flame Sensor Module - Infrared Detection 3pin module (IR)

IR Sensor Mdoule (Flame sensor)

The Fire/Flame Sensor Module is an infrared-based detection module designed for flame monitoring and fire detection applications. Using an IR receiver, this module can detect flames or light sources in the 760nm to 1100nm wavelength range. It provides a digital output signal when a flame is detected, making it ideal for fire alarm systems, robotics, and safety applications. With a compact 3-pin interface (VCC, GND, DO), it is easy to integrate with microcontrollers like Arduino, Raspberry Pi, and ESP32.
