AJMRTC LM393 3 Pin IR Flame Detection Sensor Module, Infrared Fire Detector Receiver Module for Arduino Raspberry Pi STM32, DIY Electronic Kit Fire Alarm Security Monitoring Project

AJMRTC LM393 IR flame detection sensor module uses an infrared receiving probe paired with the LM393 comparator chip to capture flame infrared radiation in the 760nm to 1100nm wavelength range. The built-in potentiometer lets you fine-tune detection sensitivity easily. It runs on DC 3.3V to 5V power and outputs digital switch signals that connect directly to MCU IO ports, requiring no extra peripheral circuits.

Power and signal indicator lights clearly show working status. The small form factor supports easy installation and wiring. It works seamlessly with Arduino, Raspberry Pi, STM32 and other microcontrollers. Suitable for fire alarm systems, flame monitoring, flame tracking robots, electronic experiments and various DIY projects. Keep in mind the module responds to infrared light sources, so use it in a suitable test environment.
