Guys,
I have an oil burner (based on a babington ball design) that i wish to start automating.
Basically the burner will occasionally go out (for any number of reasons), whihc has no effect other than that the oil pump continues to run for no good reason.
Stage 1 of my project is to try and see if a suitably positioned LDR (attached to a Picaxe) would be able to detect the presence/absence of flame and shutdown a relay to the oil pump.
Stage 2 will be to hook it up with a SimpleLan which will then send me an SMS - but that is another story !
So my thought is to get a 1/2" copper tube about 150mm long, mount the LDR at one end (which is sealed, with just the wires coming through (possibly something there to let any excess heat escape)
The other end of the tube is close to the babington ball and pointed directly at the flame (which shoots down a tube so there would be little ambient light).
Sample some numbers during operation to see if there is a threshold which is a definitive cutoff number.
Does this sound feasible or have i missed something here ?
