HQ 4 - pin flame sensor module fire source detection

Detail HQ 4 - pin flame sensor module fire source detection

hai kak. Mohon maaf untuk minimal order 20 ribu ya kak baru bisa kita proses, diluar ongkirstock per 28 juni = 50 pcs

use:
All kinds of flame, fire detection
Module Features:
1, can detect the flame or wavelength in the 760 nm to 1100 nm range of light
source, lighter test flame distance of 80cm, the greater the flame, the more
distant test distance
2, the detection angle of about 60 degrees, particularly sensitive to the flame
spectrum
3, the sensitivity adjustable (figure blue digital potentiometer adjustment)
4, the comparator output, signal clean, good waveform, drive ability, more than
15mA
5, with adjustable precision potentiometer adjustment sensitivity
6, the working voltage of 3.3V-5V
7, the output form: DO digital switch output (0 and 1) and AO analog voltage
output
8, with a fixed bolt hole, easy to install
9, small board PCB size: 3.2cm x 1.4cm
10, using a wide voltage LM393 comparator
Module instructions:
1, the flame sensor is the most sensitive to the flame, the ordinary light is
also a reaction, generally used for flame alarm and other purposes.
2, small board output interface can be directly connected with the
microcontroller IO port
3, the sensor and the flame to maintain a certain distance, so as not to damage
the sensor at high temperature, the flame test flame distance of 80cm, the
greater the flame, the more distant test

4, small board analog output and AD conversion processing, you can get a higher
accuracy
