Arduino Modules – Flame Sensor




Quick and simple start guide for using and exploring the Flame Sensor module with an Arduino.

The model in the example I am using is from Deal Extreme [DX] and can be found HERE.

(The instructable for the Rain Sensor is now available!)

Materials needed:

  • Flame Sensor (model with an analog out)
  • Male to Female jumper wires
  • An Arduino, any flavor.
  • Lighter or another flame source for testing.

Arduino Modules - Flame Sensor




Step 1: Getting to know your Flame Sensor:

Usage:
These types of sensors are used for short range fire detection and can be used to monitor projects or as a safety precaution to cut devices off / on.

Range:

I have found this unit is mostly accurate up to about 3 feet.

How it works:

The flame sensor is very sensitive to IR wavelength at 760 nm ~ 1100 nm light.

Analog output (A0): Real-time output voltage signal on the thermal resistance.

Digital output (D0): When the temperature reaches a certain threshold, the output high and low signal threshold adjustable via potentiometer.

Pins:

VCC…… Positive voltage input: 5v for analog 3.3v for Digital.

A0………. Analog output

D0……… Digital output

GND….. Ground

Dimensions:

1.18 in x 0.59 in x 0.20 in (3.0 cm x 1.5 cm x 0.5 cm)

Weight:

0.28 oz (8 g)

Step 2: Testing and Troubleshooting:

Testing:
To test the Flame Sensor and ensure that it is working correctly connect the VCC to a 5v power source and GND. Move a flame source with in a foot of the front of the Ir sensor and the D0-LED should light up.

Troubleshooting:

If the D0-LED does not light up check the following:

  • Is the power source 5v?
  • Is the ground hooked up?
  • Is the flame with in 1 foot and in Line of Sight?

If none of the previous makes the D0-LED light up, your sensor may be defective.

Step 3: Wiring to an Arduino:

To wire the Flame Sensor to the Arduino simply connect the following as shown:

Flame sensor …………… Arduino

VCC…………………………. 5v

GND………………………….GND

A0……………………………. Analog in 0
