I’m just posting this new message to have some help and tips in my new project.
I’m currently working on an alarm system, my house is equiped with wireless detector, and I succeeded to “read” and “understand” the 433 MHz signal send by the detector. As it can be show on the picture attached to this message, the transmission start with a high value of 420 µSec; then it a sequence of 1 (low value of 420 µSec followed by a high value of 840 µSec) and 0 (low value of 840 µSec and high value of 420 µSec), the signal is repeated three times, and the last numbers change according to the “value” send by the detector (low voltage, opening detected,…)
I tried to use library like RCswitch, which one is working perfectly with other wireless device, but not with those ones, and the code is very complex to be understood (at least for me).
So this is my question : which function can I use to “listen” the 433 Mhz, and start an action when the signal send by the detector is received ?
I think the function attachinterrupt can be used, but I don’t succeed to decode the 1 and 0 received by the receptor … If you have some ideas, it can be very nice to give me some precious tips !
thanks again !
