It is a fire flame detection sensor relay Module. The flame sensor can detect the flame or the wavelength at 760 nm to 1100 nm range of the light source, the test flame lighters distance of 80cm, the larger the flame, the greater the distance test.
The detection angle of 60 degrees, and the flame spectrum is particularly sensitive Sensitivity adjustable (shown in blue digital potentiometer adjustment). The comparator output directly triggers the relay.
The output bluish Terminal Block for convenient connections.
