Pir sensor wiring for nodemcu esp32

[primeroz]

> you can use any voltage with NO, NC, it just a relay contact.

Then i am not sure what do you want me to check with the `multimeter`

can you be more specific ? do you want me to check

* voltage when NO
* voltage when NC
* Resistance when NO
* Restistance when NC

?

Never mind, i moved the sensor to another board where i don't have such a mess of connections and configuration, simply configured as

```
binary_sensor:
- platform: gpio
pin:
number: 5
inverted: false
mode:
input: true
pullup: true # So that it fires when the sensor is disconnected and stop flapping
name: "PIR 1"
id: pir1_motion
device_class: motion
filters:
- delayed_on_off: $sensor_debounce_time
```

and it works as expected.

* When there is no sensor connected to GPIO5 -> Binary sensor is ON ( Good )
* When the NO is connected to GPIO5 -> Binary sensor is always ON and turn off when movement is detected ( Good )
* When the NC is connected to GPIO5 -> Binary sensor is always OFF and tunr ON when movement is detected ( which is what i need )


Thanks
