I bought a small flame photodiode for a robot Im currently working on. Being a "flame" photodiode I thought it would ignore most light and pretty much only output whenever it gets light from a flame but it seems normal day light can set it off. Even lamps or sealing lights seem to be enough for it.
Pretty much almost makes it a reguarl photodiode.
I can get the data from it with this line of code: FlameValue=analogRead(0);
Just read the analog pin.
Anyway I can maybe fine tune it better for flames?
The photodiode is just
The photodiode is just reacting to the IR-light that is emitted by the flame or -very less by a light bulb- so every light source that gets hot or just warm emits IR-light so your value climbs up.So if you want to activate an alert I think you should do somethig like:
If (FlameValue > 500){
Serial.println(“Flame detected!”);
}
I think a flame emits more IR-light than a normal light bulb because it’s hotter so activateing the alert not until the Value reaches a for a flame specific value would solve the trouble with a normal bulb.Hope I can help you.
Also it would be good to
Also it would be good to verify that whatever you use for a straw is opaque to IR light.
