5 Way IR Infrared Flame Fire Sensor Module is a high precision 5-channel flame detection module designed for wide-area fire detection, robotics, automation, and safety systems in Bangladesh. This 5-channel flame sensor uses five infrared flame detectors arranged at 30-degree angles to provide a detection range greater than 120 degrees, making it ideal for detecting fire from multiple directions simultaneously. The module supports both analog and digital outputs, allowing flexible integration with Arduino, Raspberry Pi, ESP32, and other microcontrollers. With onboard potentiometer for sensitivity adjustment, LED indicators for real-time status monitoring, and high-accuracy 1% resistors, this flame sensor module delivers reliable, stable, and precise fire detection performance. It is sensitive to infrared radiation in the 700nm–1100nm wavelength range and can detect flame sources up to 80cm for lighter flames and even farther for larger flames.
