Join David Ross for an in-depth discussion in this video Select a motion detector, part of Raspberry Pi: Home Monitoring and Control.
- There are two basic kinds of motion detectors,…wired and wireless.…For a wired motion detector,…you have to run two wires to the receiving unit.…You can easily determine with a volt meter…when motion is being detected.…However, running two wires especially…over longer distances is not always desirable.…The wireless motion detector can wirelessly transmit…to the receiver without the need of wires.…Even though there are a lot…of wireless motion detectors out there,…the Skylink wireless motion detector receiver pair…is not only very good value for the money,…but is also easy to connect its receiver…to the Raspberry Pi GPIO pins.…
The receiver module can work…with up to four motion detectors,…any one of which can trigger an alarm condition.…For our purposes,…we will simply use one motion detector…with the receiver module,…even though you can later add…up to three more motion detectors if you wish.…Please note, however, (laughs)…that each motion detector is more expensive…than the receiver unit.…For the purposes of this project,…
This DIY electronics project provides simple directions for getting your home monitoring system up and running. Author David Ross helps you select a power supply, camera, motion detector, enclosure, and other components and accessories, and make your system "smart" by connecting to web services frameworks such as Weaved and WebIOPi. Then he helps you program the logic to make your Pi camera take pictures and stream video, connect to home peripherals, and mount your alarm system. With this training, and a little elbow grease, you can create a fully autonomous system that helps you and your family feel more secure at home and away.
Note: These instructions work with Raspberry Pi B, Raspberry Pi B+, and Raspberry Pi 2 models.
- Selecting hardware, including a Raspberry Pi camera and a Pi Cobbler
- Configuring VNC, SSH, and WebIOPi services
- Sending SMS messages with the Raspberry Pi
- Taking and accessing pictures remotely
- Setting up video streaming with a Raspberry Pi camera
- Connecting the Pi to the development board
- Connecting the relay and motion detector
- Programming the alarm in Python
- Mounting and securing the alarm system
