Just wondering if anyone has ever got the BL412 PIR sensor working with an ESP 32 or similar thought ESP home on home assistant. I can’t seem to find much information about them.
They are just a PIR sensor, pin 2 is for the signal on timer, just connect to ground and the other pins like a 3 pin PIR.
- Connect pin #1 to ground
- Connect pin #2 to ground (on time of 2 seconds)
- Connect pin #3 to 3.3V
- Connect pin #4 to GPIO
Thanks I’ll give it a try
