I have the following signal from a temperature sensor (broadcasts on 433.92 MHz, apparently as ASK).
I cannot for the life of me extract the temperature data.
I've tried reading off the bits in so many different ways (mostly by looking at the pulse widths) then searching the data for the temperature info.
This corresponds to a temp of 21.0.
I tried to read each pulse after the first 4 big pulses - that gives 37 bits:
Then I tried searching just for the 21 part. So I tried searching for 21, 61, 71 (in case the designer was adding 40 or 50 degrees to avoid negative numbers). I tried searching for the 2 and then the 1 bit shifted by 4. I tried negating all the bits. I tried searching in reverse.
Is it possible this is not pulse width modulation? Is it possible there are not 37 bits here?
