Hijack a motion detector - hardware?
I have a motion detected lamp in the garden.
I want to hijack the motion detector and connect it to my network.
What hardware can i use to connect and read if there is motion?
I guess its some sort of current sensor, because i cant direct connect it to Arduino since voltage is to high.
@sundberg84 LDR or light sensor? (at least cheaper..)
Yea, but i guess it will register motion during daytime?
You can use an optocoupler, I have done so to read an 12V signal from my alarm system. Check CNY17 for example.
Cool! I will try and get back here with my findings Tnx!
