IR Flame Sensor

A compact infrared flame detection sensor that outputs a digital or analog signal the moment it detects the IR signature of an open flame. With fast response time and high photo sensitivity across the 760–1100 nm range, it's ideal for fire detection in robotics competitions, safety systems, and automation projects where a microcontroller handles the response logic.

🔹 Key Applications
