The IR Flame Detection Sensor Module is designed to detect infrared light emitted by flames. Capable of sensing flame sources from a distance of up to 80 cm (depending on intensity), it outputs a digital signal that can be easily read by microcontrollers like Arduino, ESP32, or Raspberry Pi.
Operating at 3.3V to 5V, the sensor includes an onboard comparator for clean digital output and an adjustable sensitivity via potentiometer. It’s perfect for building fire detection alarms, safety robots, and flame-sensitive automation systems in smart homes or industrial settings.
Whether you're working on a fire detection robot, an environmental monitoring system, or a smart alarm, this module offers quick, reliable performance in compact form.
