What does it do?
The sensor has two outputs, an analogue output that is
dependent on how strong a flame is detected, or a digital output that will go high if a flame is detected above a threshold set by the modules potentiometer. This example program reads the status of both sensor outputs and outputs the result to the UART.
Pinout:
1 Analogue out
2 GND
3 VCC (+5V)
4 Digital out
