3 needle flame sensor module fire source detection module infrared receiving module fire light detection

use:
Various flames, fire source detection
Module characteristics:
1. You can detect light sources in the range of flames or wavelengths in the range of 760 nanometer to 1100 nanometer. The lighter testing the flame distance is 80cm. The larger the flame, the farther the test distance of the test.
2. The detection angle is about 60 degrees, which is particularly sensitive to the flame spectrum
3. The sensitivity can be adjusted (the blue digital potentiometer is adjusted in the figure)
4. The output of the comparator, the signal is clean, the waveform is good, the driver capacity is strong, more than 15mA
5. Match the adjustable precision potentiometer to adjust the sensitivity
6. Work voltage 3.3V-5V
7. Output form: Do digital switch output (0 and 1) and AO analog voltage output
8. There are fixed bolt holes for easy installation
9. Small board PCB size: 3.2cm x 1.4cm
10. Use width voltage LM393 comparator
Module use instructions:
1. The flame sensor is the most sensitive to the flame, and it also responds to ordinary light. Generally, it is used as a flame alarm.
2. Small board output interface can be directly connected to the single -chip machine IO port
3. Keep a certain distance from the sensor and the flame, so as to avoid damaging the sensor at high temperature. The distance between the flame test of the lighter is 80cm. The larger the flame, the farther the test distance

4. Small board analog output method and AD conversion processing can get higher accuracy
