PIR sensor in a big room

Hardware
1

I do have a big livingroom, which I can divide in 3 zones

  • zone A in the back
  • zone B in the front
  • zone C, a passage zone for going to stair going to the upper floor.

What would be the best way to dispose PIR sensors wich trigger lights only if there are persons in that particular zone.

Yes, I don’t understand what you mean… :slight_smile:

At a guess, you want something like GitHub - bruhautomation/ESP-MQTT-JSON-Multisensor: (OBSOLETE) ESP MQTT JSON Multisensor for Home Assistant. Supported sensors include the TEMT6000 light, AM312 PIR, DHT22 temperature/humidity sensors. RGB led supports flash, fade, and transition. Over-The-Air (OTA) uploading, too!

PIR sensors are line of sight for a fairly large distance and arc, like a slice of pie. I think mine are 15 feet.

So you may need to use some trial and error to see how you can position sensors and then use automation logic for your conditions… i.e. if pir1 and pir2 are tripped, then I must be in zone A, not zone B.

I did something similar to figure out when someone was going up the stairs from the basement so that I could turn on a light in the kitchen.
