Imagine you are trying to photograph a rare bird without startling it, or want to ensure that you have photographic evidence if your house is broken into. These are just a few of the possibilities that this project from Instructables member and Freetronics customer ASCAS open up. The project consists of a motion detecting module which wirelessly communicates with the remote receiver connected to the camera. This allows you to position your motion detector separately to your camera for added flexibility. The tutorial is easy to follow, informative and you are sure to learn a lot while you create your new automatic camera trigger! To get started check out the following link.
The wireless functionality in this project is based on a 433MHz wireless connection. These types of connections are very common and have the potential to be used in many different projects.
