Simple Fire Sensor - Detecting and maesuring fire with regular fire sensor (example)

This page contains a simple example with function documentation on how to detect and measure intensity of fire with the sensor.

Initialization

To use the sensor, first include the required library, create the sensor object and SimpleFireSensor object, and initialize it in the setup() function. You can use the return value of begin() to check if everything is connected correctly.

#include "Simple-fire-sensor-easyC-SOLDERED.h"

#define ANALOG_PIN 14
#define DIGITAL_PIN 15

SimpleFireSensor sensor(ANALOG_PIN);
void setup() {
  sensor.begin();
}
//...

SimpleFireSensor sensor()

Creates SimpleFireSensor object

Returns value: none

Function parameters:

Type	Name	Description
`uint16_t`	`pin`	Analog pin number for data communication

sensor.begin()

Initializes the sensor.

Returns value: Returns true if initialization is successful, false otherwise.

Measuring with both digital and analog output

In this library, there are two options for displaying the analog value: for a percentage value, call the getValue() function, and for the raw value, call the getRawValue() function.

#include "Simple-fire-sensor-easyC-SOLDERED.h"

#define ANALOG_PIN 14
#define DIGITAL_PIN 15

SimpleFireSensor sensor(ANALOG_PIN);
void setup() {
  Serial.begin(115200);
  sensor.begin();
}

void loop() {
  Serial.print("IR light sensor reading: "); // Print information message
  Serial.print(sensor.getValue());           // Prints percentage value of fire sensor
  Serial.print("% ");
  Serial.println(sensor.getRawValue());        // Prints raw value of fire sensor

  if (digitalRead(DIGITAL_PIN)) // Potentiometer on breakout board is used to
                                // set threshold value. This function checks if
                                // the threshold value is passed and determines if there
                                // is a fire nearby.
  {
      Serial.println("Fire is not detected.");
  }

  else
  {
      Serial.println("Fire is detected!!");
  }

  // You can also use thresholds (except threshold for LED) like in the Read_values_easyC example to detect fire.

  // Wait a bit before the next reading
  delay(500);
}

sensor.getValue()

Returns the measurement in percentage.

Returns value: Returns float representation of fire chance percentage

sensor.getRawValue()

Returns the raw ADC value.

Returns value: Returns integer representation of fire value

Sensor when fire is not present

Serial Monitor output
