2 Channel Flame Sensor Module Fire Detection Fire Source Sensor Module Infrared Reception
Specificatii:
1. It can detect flame or light source with wavelength in the range of 760 nm to 1100 nm. The flame distance of the lighter is 80 cm. The larger the flame, the farther the test distance is. 2. The detection angle is about 60 degrees, which is especially sensitive to the flame spectrum.
3, the sensitivity is adjustable (blue digital potentiometer adjustment in the figure)
4, the comparator output, the signal is clean, the waveform is good, the driving ability is strong, more than 15mA.
5, with potentiometer adjustment sensitivity
6, working voltage 3.3V-5V
7, output form: digital switch output (0 and 1)
8, with fixed bolt holes for easy installation
9, small board PCB size: 3.2cm x 1.7cm
10. Use a wide voltage LM393 comparator
Module instructions:
1. The flame sensor is most sensitive to flame and is also reactive to ordinary light. It is generally used for flame alarms and other purposes.
2, the small board output interface can be directly connected to the IO port of the microcontroller
3. The sensor and the flame should be kept at a certain distance to avoid damage to the sensor at high temperature.
