It is ideal for fire alarm systems, robotics, and industrial safety automation. With adjustable sensitivity, it responds reliably to small flames from candles to large burners.\u003c\/p\u003e\u003ch2\u003eKey Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e5V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDetection Angle\u003c\/td\u003e\n\u003ctd\u003e60°\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDetection Spectrum\u003c\/td\u003e\n\u003ctd\u003e760 nm - 1100 nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Type\u003c\/td\u003e\n\u003ctd\u003eRelay (NO, NC, COM)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eComparator IC\u003c\/td\u003e\n\u003ctd\u003eLM393\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensitivity Adjustment\u003c\/td\u003e\n\u003ctd\u003eOn-board potentiometer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/arduino-gsm-sms-kit-build-an-iot-button-that-sends-messages\"\u003eAutomatic fire alarm system with SMS alerts using GSM module\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003eFlame-seeking robot for firefighting competitions\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/esp32-home-assistant-kit-control-4-relays-and-6-sensors\"\u003eSmart home fire detection integrated with Home Assistant\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/esp32-industrial-relay-control-kit\"\u003eIndustrial burner monitor with relay-triggered shutdown\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCompatibility\u003c\/h2\u003e\u003cp\u003eWorks with any 5V microcontroller including Arduino Uno, Mega, Nano, ESP8266, ESP32, and Raspberry Pi (with level shifting). The digital output connects directly to a GPIO pin, and the relay can switch high-current loads up to 10A at 250V AC. Common pairings include buzzer modules, water pumps, and solenoid valves for automated response.\u003c\/p\u003e\u003ch2\u003eWiring Notes\u003c\/h2\u003e\u003cp\u003eConnect VCC to 5V, GND to ground, and the DO pin to a digital input on your microcontroller. The relay contacts (NO, COM) handle the load circuit. Ensure flame exposure does not exceed the sensor's temperature limit; keep plastic housing away from direct flame. Use a pull-up resistor if interfacing with 3.3V systems.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
