Whether you wonder or not makes no difference to me, I actually need to update my signature as I left Humai, probably I should update it with Semi Finalist in Global Mobile Innovators Tournament in the Smart Home Category, first phase winner in Microsoft / Arduino World Maker Challenge, Bizspark Member, I could go on and all accomplished before I had ever touched an ESP which is hardly the entire IoT, so don't start getting rude, this is actually the first forum I have encountered where the people are actually nice and it is an enjoyable experience to use it.
GPIO2 is connected to the sensor, when the sensor detects it triggers CH_PD to high which turns on the ESP and when nothing detected it is set to low as far as I could tell. On my ATMEGA version, the ATMEGA send high to CH_PD which turns on the ESP and low to turn it off, so maybe the terminology was not correct but that is what is happening I believe.
The sensor is the following and has digital output which is connected to GPIO2 in my case.
