Make A Raspberry Pi Parent Detector #piday #raspberrypi @Raspberry_Pi

Raspberry Pi Learning Resources

Make a video triggering motion detector with Raspberry Pi. via raspberrypi.org

A Raspberry Pi is so small that it can easily be hidden; that makes it the perfect tool for this kind of project. The basic idea is to use motion detection to trigger video recording via the Raspberry Pi Camera Board. You can then leave the Pi hidden in your room and see who’s been caught on camera when you get home from school.

LESSON OBJECTIVES

Understand a Passive Infra Red motion sensor
Understand how to use the picamera Python module
Understand how to record videos
Understand how to play back videos
LESSON OUTCOMES

To have built and tested a Raspberry Pi parent detector
Caught someone on camera
Gained experience in Python programming
Gained experience using the Raspberry Pi GPIO pins

REQUIREMENTS

As well as your Raspberry Pi and all its standard peripherals, you’ll need:

HARDWARE

Raspberry Pi Camera Module
PIR motion sensor module (try eBay)
Female-to-female jumper wires, at least 3 (try eBay)

SOFTWARE

python-picamera

EXTRAS

Camera Board 360 Gooseneck Mount (from modmypi.com) or equivalent

TIME REQUIRED

1-2 hours

STEPS

Connect the PIR motion sensor
Test the PIR motion sensor
Setting up the Camera Board
Install the picamera Python module
Program the camera to preview on movement
Recording to a file and playing back
Stealth mode
