135038 Arduino Flame Detection Sensor Module

Arduino Flame Detection Sensor Module Also : http://www.hobbycomponents.com/index.php?route=product/product&product_id=144

Sensor for flame wavelengths between 760 nm to 1100 nm infrared is most sensitive; Module has two outputs: 1, AO, analog output, real-time output voltage signal on the thermal resistance; 2, DO, when the temperature reaches a certain threshold, the output high and low signal threshold adjustable via potentiometer; 60 degree detection sensor. Voltage: DC 3~5.5V

This is a simple example of how to use the HobbyComponents Arduino flame detection
module (HCARDU0024). 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.

SENSOR PINOUT:

PIN 1: Analogue out
PIN 2: Ground
PIN 3: +5V
PIN 4: Digital out
