All kinds of flames, fire detection source
1, it can detect flame or wavelength in the range 760 nm to 1100 nm range of light, lighter flame test distance of 80cm, for the greater flame, the farther distance test
2, the left and right detection angle of 60 degrees, particularly sensitive to flame photometry
3 adjustable sensitivity?The blue digital potentiometer adjustment?
4, the comparator output signals clean, good waveform, driving ability, than 15mA
5, with adjustable precision potentiometer sensitivity adjustment
6, the working voltage of 3.3V-5V
7, the output format: Digital switching output?0 and 1?
8, a fixed bolt hole for easy installation
9, small PCB board size: 3.2cm x 1.4cm
10, using a wide voltage comparator LM393
1, the flame sensor to the flame of the most sensitive to ordinary light is also a reaction, generally used as fire alarm and other purposes.
2, a small plate output interface can be directly connected to the microcontroller IO port
3, and the flame sensor to maintain a certain distance, so as not to damage the temperature sensor, the flame of a lighter test distance of 80cm, for the greater flame, the farther distance test
