This flame detection module uses a specialized high-speed photodiode designed to sense light wavelengths emitted by fire within the 760 nm to 1100 nm spectrum. It detects naked flames or light sources within a 60-degree detection angle at distances up to 100 cm. With both analog signal output for intensity measurement and a digital output with adjustable sensitivity, it is well-suited for fire-fighting robots, boiler flame monitoring, industrial safety hazards, and automatic fire alarm systems.
