Relay Module with Light Sensor
- Can detect the flame, or wavelength of the light source in the range of 760 nm to 1100 nm, and the the lighter test flame distance is 80cm, the greater the flame, the test distance farther
- Detection angle of about 60 degrees, the flame spectrum is particularly sensitive
- Adjustable sensitivity (shown in blue digital potentiometer adjustment)
- The comparator output directly trigger the relay
- The output with the blue wire holder, wiring
- The flame sensor flame most sensitive reaction to sunlight, is generally used as flame alarm purposes.
- By adjusting the potentiometer, can be set to a sensor sensing the intensity of the flame, when the flame exceeds a set threshold value, the relay is energized, the common terminal and the normally start is turned on, and when the flame is lower than the set threshold value, the relay is disconnected, the common terminal and the normally closed terminal is turned on;
- The public side, normally open, normally closed three ports, the equivalent of a dual-control switch, relay coil power, public end and often the beginning of conduction, radio, the common terminal and the normally closed terminal is turned on;
- The sensor and the flame to keep a certain distance to avoid high temperature damage to the sensor, lighter test flame distance of 80cm, the greater the flame, the test distance farther
