Arduino Flame Sensor Alarm using KY-026

Hello world! in this little instructable i will show how to use the KY-026 Arduino Flame Sensor as a alarm.
It’s multifunctional, for example you can use it to alarm you that your racing cars brakes are getting Red Hot.
Or use it with a sprinkler attached to it when it senses flames for example flames with no smoke, so a smoke detector cannot be used, it will also detect much quicker then a smoke alarm. It’s Just an example. Anyways it has use for many things, like deactivating a fuel line such as a propane or a natural gas line, and activating a fire suppression system. It could also notify you that a flame is still there for some industrial purposes.. so much more i think.

To turn a device on or off is easy to do in the code.

I just made this code for the Arduino Flame Sensor quickly for this Instructable, you can play with it a bit.

Parts list:
Arduino uno. I used the RobotDyn Uno, a real good chinese copy with 7 analog pins.
Relay Ky-019
Flame Sensor Ky-026
red & green led.
Push button for reset (optional)
Lamp with fitting and power cable to connect to the relay to test the alarm, or just an alarm strobe (optional)
