ProductDescription : Product Description
Feature:
1. It can detect flame or light source with 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 particularly sensitive to the flame
3, the sensitivity is adjustable (blue digital potentiometer adjustment in the figure)
4, the comparator output, the signal is clean, the driving ability is strong, more than 15mA
5, with adjustable precision potentiometer to adjust sensitivity
6, working voltage 3.3V-5V
7, output form: digital switch output (0 and 1) and voltage output
8, with fixed bolt holes for easy installation
9, small board PCB size: 1.26inchx0.56inch/3.2cm x 1.4cm
10. Use a wide voltage LM393 comparator

Product wiring description:
VCC: 3.3-5V power supply "+"
GND: power supply "-"
DO: TTL switch signal output.
AO: analog signal output (voltage signal)

Module instructions:
1. The flame sensor is most sensitive to flame and is also active 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 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. The flame distance of the lighter is 80cm. The larger the flame, the farther the test distance is.
4, small board output mode can achieve higher precision
