KC868-A8 with Motion Sensor HC-SR501 - vijjav - 07-06-2023
I need help connecting pir motion sensor with A8 board. Should i connect with DI 1-8 or s2, s3 terminals?
Here is the code part I am currently using.
Code:
switch:
- platform: gpio
name: "Study Room PIR"
id: a8_study_room_pir
pin:
pcf8574: pcf8574_hub_out_1
number: 7
mode: OUTPUT
inverted: false
binary_sensor:
- platform: gpio
name: "a8_study_room_pir"
device_class: motion
# on_press:
# then:
# - switch.toggle: a8_study_room_pir
pin:
pcf8574: pcf8574_hub_in_1
number: 7
mode: INPUT
inverted: falseRE: KC868-A8 with Motion Sensor HC-SR501 - admin - 07-06-2023
if your PIR sensor is dry contact signal, all port can use. just DI1-8 support wire long distance, support 300 meter wire no problem. S2, S3 port by short distance.
suggest use DI1-8 port.

I've connected my PIR to D8, but my output got stuck at "Cleared".
I did a wire short test between D8 and GND, no response.
But when is short D8 with +12V , then the pir got detected and released when short is disconnected.
It is suppose to be D8 vs GND, what I am missing here?

what D8?? DI8? it set by your PIR sensor use by "NC" or "NO". A8 digital input just use by 0v or 12v logical voltage.

I use DI terminal 8 and PIR uses NO
This is the PIR sensor I am using https://components101.com/sensors/hc-sr501-pir-sensor

change the config line:
inverted: false ----> inverted: true

I've changed the config inverted as true.
- platform: gpio
name: "a8_study_room_pir"
device_class: motion
on_press:
then:
- switch.turn_on: a8_study_room_pir
on_release:
then:
- switch.turn_off: a8_study_room_pir
pin:
pcf8574: pcf8574_hub_in_1
number: 7
mode: INPUT
inverted: true
But still is not getting detected, after changing inverted as true, Motion detection is inverted when shorting D1 8 with +12 V.
Which means when motion detected the logs says it is cleared, and motion clear inverted as detected.

open your PIR sensor, maybe inside on PCB have jumper, it can set "NO" or "NC", you can chose it.
