Fire Flame detection Sensor Relay Module

It is a flame detection sensor relay module. The flame sensor can detect the flame or the wavelength in the 760 nm to 1100 nm range of the light source; the test flame lighter's distance is 80 cm. The larger the flame, the greater the distance test. The detection angle is 60 degrees, and the flame spectrum is particularly sensitive. Sensitivity is adjustable (shown in the blue digital potentiometer adjustment). The comparator output directly triggers the relay. The output is a bluish terminal block for convenient connections. Package Includes: 1 x Fire Flame detection Sensor Relay Module
