Overview

Me Flame Sensor can be used to detect fire source or light source with wavelength in the range of 760 nm to 1100 nm. Its detection angle is up to 60 degrees, and detection accuracy can be adjusted. When the flame is detected, its blue indicator will light on. It can be applied to the safety monitoring projects such as fire-fighting robot and flame alarm. The port of this module has black ID, and RJ25 cable can used to connect to the port with black ID on Makeblock Orion.

Pin definition

The port of Me Flame Sensor has three pins, and their functions are as follows:微信截图_20160129135537

Wiring mode

● Connecting with RJ25
Since the port of Me Flame Sensor has black ID, you need to connect the port with black ID on Makeblock Orion when using RJ25 port. Taking Makeblock Orion as example, you can connect to ports No. 6, 7, and 8 as follows:微信截图_20160129135616

● Connecting with Dupont wire
When the Dupont wire is used to connect the module to the Arduino UNO Baseboard, its DO pin should be connected to digital port, and its AO pin should be connected to analog port as follows:

Guide to programming

● Arduino programming
If you use Arduino to write a program, the library Makeblock- Library-master should be invoked to control the Me Flame Sensor. This is a routine to identify if there is flame by this module through Arduino programming.微信截图_20160129135754

Read the detection result from Me Flame Sensor, and output the result to the serial monitor in Arduino IDE. Upload the code segment to Makeblock Orion and click the Arduino serial monitor, and you will see the running result as follows:微信截图_20160129135900

Principle analysis

The flame is composed of various combustion products, intermediates, high temperature gases, hydrocarbons, and high temperature solid particles (mainly the inorganic materials). The thermal radiation of the flame has gas emission with discrete spectrum and solid radiation with continuous spectrum. The radiation intensity and wavelength distribution of flame varies from burning objects. Generally the near-infrared light of flame has great radiation intensity. Me Flame Sensor is made on the basis of this feature.
Me Flame Sensor can detect the infrared light with wavelength from 700 nm to 1200 nm. When the infrared wavelength is near 940 nm, it reaches the highest sensitivity. The probe of Me Flame Sensor converts the intensity of surrounding infrared light into the change of current, and then implements analog-to-digital conversion (ADC) to identify whether there is fire nearby.
