Introduction
This module is sensitive to the flame, while could also detect common light. Usually used as a fire alarm.
On board, digital output interface can be directly connected to microcontroller IO.
Please keep a distance with flame, high temperature may damage the sensor module.
 
Description

2. Detection angle about 60 degrees, it is sensitive to the flame spectrum.
3. Accuracy adjustable
4. Operating voltage 3.3V-5V
5. Output
a. analog voltage output
b. digital switch outputs (0 and 1)
6. With a screw hole
7. PCB size: 3cm * 1.6cm
8. Power indicator (red) and digital switch output indicator (green)
9. Comparator chip LM393, which is stable.
 
Interface Description (4-wire)
