pibooth-pir-sensor

pibooth-pir-sensor is a plugin for the pibooth_ application.

PIR sensor for Pibooth. :raw-html:  It plays a random sound & turn on a light when there are motion. :raw-html:  If someone activate the PIR-sensor, after a 2 minute countdown period has expired without any motion. :raw-html:  That way it can turn on a light, and say "Hello, wanna take a photo" too a person if they walk by the Pibooth Selfiecam.

This is not a plugin yet, run it in the background.

Requirements

Hardware ^^^^^^^^

1 Raspberry Pi 3 Model B (or higher) :raw-html: 
1 PIR sensor hc-sr501 or hc-sr505 Mini (but any PIR will work) :raw-html: 
2 Ferrite 2810138-50r-10 - "you can also use hf30acb321611-t". Or as we done in this project 1 Clip On Soft Ferrite Ring, around all 3 wire :raw-html: 
1 LED :raw-html: 
1 Resistors 1 x 100 Ohm :raw-html:

Configuration

Most commen PIR-sensors hc-sr501, hc-sr505 Mini :raw-html:  Here we use an hc-sr501, but it works with any PIR-sensor

Set the jumper to single trigger.
Set the delay all the way to the left 0.3 sec.
Set the Sensitivity/Distance all the way to the right. (lower it if you need to, or use trick 1 or 2).

Tricks ^^^^^^ Tricks to make PIR, less sensitive but still respond. There are 2 things you can do. :raw-html:  First take off the Fresnel Lens "white plastic cover".

Take an old ball pen and use the plastic or rubber part by putting it over the PIR sensor, to make the PIR work more direct.
Or fill the Fresnel Lens "white plastic cover" with some paper towel or tin foil, except for a small hole. :raw-html:  IMPORTANT, make shure the tin foil does not have contact with the circuit board.

Wiring

PIR - look at your PIR for correct details

VCC: Pin (5v) - You can use 3.3V, but many PIRs make more false motion with only 3.3v
OUT: Pin-GPIO (OUT) - Never source or sink more than 0.5 mA into an GPIO input pin, you can use a resister to prevent that
GND: Pin (GND)

Ferrite ^^^^^^^ To prevent false motion, you can use Ferrite etc a Clip On Soft Ferrite Ring around the 3 wire :raw-html: 

.. image:: https://github.com/DJ-Dingo/pibooth-pir-sensor/blob/master/templates/ferrite_pir.png :align: center :alt: PIR-sensor Wirring

Or you can solder a Ferrite 2810138-50r-10 or hf30acb321611-t between the wire from the GPIO and VCC on the PIR :raw-html:  And again a Ferrite 2810138-50r-10 or hf30acb321611-t between the wire from the GPIO and OUT on the PIR.
