Hi, I used some old stock I had kicking about in the workshop KC7783R's which is a 5 to 12V PIR, I used a 1K /2K resistor divider on the output line to give 3.3V.

EDIT: Another thought. Which ESP module or development board ae you using? Some have a 10K pull up on CH_PD, that could change things, I used an ESP8266-01.
