A wildlife camera with a motion detection feature sounds like an expensive piece of equipment. But in reality, when you look at the parts needed to put together this DIY photography project, it is definitely one of the cheapest for a bit of amateur photography.
To help out there are the step by step instructions with a detailed list of materials and parts. The cheap motion detection camera is built around a low cost key chain digital camera that you can pick up from a supermarket shelf. The innovative motion detection that sets off the camera comes from a PIR sensor module hacked from an Air Wick Freshmatic Air Freshener. A microcontroller and transistors along with some soldering is all it takes.
