Sketches: Flame Detection Sensor Module

HCARDU0024_800
Flame Detection Sensor Module

Items you will need:

Arduino development board such as this one

Male to female dupont cables

Flame detection sensor module

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
