I'm trying, what I thought would be simple, to wake a sleeping ESP8266 via motion detected by a PIR.
There are a lot of schematics around and they all seem to go about it more or less the same way, and the simplest form seems to be this:
Where RST is the RST pin of the ESP8266 and Trigger is the PIR's trigger line.
The problem I'm finding is that this is not working.
The PIR is working fine, and throws out almost 3v for 2 seconds when triggered and 0 when no motion is detected.
My ESP is being woken up when the PIR trigger is OVER, not when it STARTS. So if the PIR senses motion for a long time, the ESP will only wake up when the motion STOPS.
The PIR is one of these.
What am I doing wrong here?
