PIR sensor with ESP32 WROVER hardware issue

Postby Meghana » Tue Aug 06, 2019 11:35 am

Hello all,
Here is the issue I am facing with pir sensor when connected to ESP32 WROVER board.
I have made GPIO4 as pir sensor pin. when connected to power supply board the pir is showing continuously high occupancy. Even in order to get accurate output i havae connected 10k resistor between output and ground pin for false detection.
I even checked with the connectivity using multi meter and everything is fine.
I am not getting what may be the issue.
even i made other GPIO i.e 18(gpio) as pir sensor pin. But here also same issue i am getting same issue.
kindly let me know the solution.

it's more helpful for people to help when you share other information.
i.e. the sensor your using, how its all wired up, and most importantly your code.
