Hi peepz in this little instructable i will show how to use the KY-026 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 quickly for this Instructable, you can play with it a bit.
Step 1: Schematic Code and Parts List.
Here is the schematic and Parts list.
What do you need?
- 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)
- Bunch of MM FF FM Jumper wires.
If you build something from it, just share it in the comments!
