Project34.Flame Sensor Module
==============================

Description
------------
The KY-026 Flame Sensor module detects infrared light emitted by fire. This 
module has both digital and analog outputs and a potentiometer to adjust the 
sensitivity. Commonly used in fire detection systems.

Compatible with Arduino, Raspberry Pi, ESP32 and other microcontrollers.



Specification
--------------
- Operating Voltage	3.3V ~ 5.5V
- Infrared Wavelength Detection	760nm ~ 1100nm
- Sensor Detection Angle	60°
- Board Dimensions	1.5cm x 3.6cm

.. code-block:: c

    int led = 13; // define the LED pin
    int digitalPin = 2; // KY-026 digital interface
    int analogPin = A0; // KY-026 analog interface
    int digitalVal; // digital readings
    int analogVal; //analog readings

    void setup()
    {
    pinMode(led, OUTPUT);
    pinMode(digitalPin, INPUT);
    //pinMode(analogPin, OUTPUT);
    Serial.begin(9600);
    }

    void loop()
    {
    // Read the digital interface
    digitalVal = digitalRead(digitalPin); 
    if(digitalVal == HIGH) // if flame is detected
    {
        digitalWrite(led, HIGH); // turn ON Arduino's LED
    }
    else
    {
        digitalWrite(led, LOW); // turn OFF Arduino's LED
    }

    // Read the analog interface
    analogVal = analogRead(analogPin); 
    Serial.println(analogVal); // print analog value to serial

    delay(100);
    }
