FIRE / FLAME DETECTING SENSOR RELAY MODULE
General Description:
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 lighter 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 is adjustable (shown in blue digital potentiometer adjustment). The comparator output directly triggers the relay. The output bluish Terminal Block for convenient connections.
Working Principle:
A fire flame-detecting sensor relay module operates by utilizing a flame sensor to detect infrared radiation emitted by flames. When flames are detected, the sensor triggers a relay, which can activate alarms, shut down equipment, or initiate other safety measures. These modules are essential components in fire detection and safety systems, providing early warning and helping to prevent potential hazards. Regular calibration and integration into larger safety systems ensure their effectiveness in various environments.
