There is a wide range of flame sensors, which you can connect to the ConceptBoard. Here is an example of conneting one of them. When it's done flame alarms are ready to be reported to the cloud via a cellular network.

 

- We have used 1-Channel Flame Sensor Module for Arduino (e.g. http://www.dx.com/p/1-channel-flame-sensor-module-for-arduino-blue-152020#.Vw4mI_mLSM8)

- sensor has three lines, it ***** to be connected to GND, 5V and GPIOx (we have used GPIO8)

- sensor's sensitivity is adjustable with built-in potentiometer
