Flame Sensor Fire Detection Module Infrared Receiving Three Needle | Обустройство дома

Uses:
Various flame, fire detection
Module feature:
1, can detect the flame or wavelength in the range of 760 nm to 1100 nm light source, the lighter test flame distance is 80cm, the greater the flame, the test distance is far
2, the detection angle of 60 degrees, the flame spectrum is particularly sensitive
3, the sensitivity can be adjusted (figure in blue digital potentiometer adjustment)
4, the comparator output, the signal is clean, waveform is good, driving ability, more than 15mA
5, with adjustable precision potentiometer adjustment sensitivity
6, working voltage 3.3V-5V
7, output form:DO digital switch output (0 and 1) and AO analog voltage output
8, with fixed bolt hole, easy to install
9, small size: 3.2cm x 1.4cm PCB
10, the use of wide voltage LM393 comparator
Module description:
1, the flame sensor is the most sensitive to the flame, the ordinary light is also a response, the general use of flame alarm.
2, small output interface can be directly connected with the microcontroller IO port
3, the sensor and the flame to maintain a certain distance, so as to avoid high temperature damage sensor, the test flame distance of the lighter 80cm, the greater the flame, the more the test distance
4, small analog output mode and AD conversion process, can obtain higher accuracy
