This was a 2006 individual thesis project completed by Christopher A Bray.

Project Title

Project Abstract

Conservationists use ‘camera traps’ to automatically photograph passing wildlife in remote-area studies, but all existing systems require human presence to retrieve images. This thesis prototypes a wireless camera trap network that emails the photographs to the researcher, via Iridium satellite. The Remote Module (RM), controlled by a CC1010 microprocessor, is tripped by a UPD or PIR motion sensor, and the animal’s photograph is taken by a CMOS camera and can be accompanied by environmental data such as temperature. The RM then transmits the image wirelessly over the 433 MHz ISM band to a nearby Base Module (BM). Up to ten RMs can be wirelessly linked to one BM, automatically forming a cohesive star topology RF network. The BM is also controlled by a CC1010 microprocessor. Here data packets are error-checked and sent to the BM’s laptop over a serial link where it is encoded and sent as an email. The BM can also check its own email account to receive test commands. Real-time considerations reduce the chance of interference caused by multiple modules wishing to transmit simultaneously, and power-saving strategies have been implemented to increase their operating life.

This project utilises the 'Wireless Sensor Networks Platform' developed as an earlier thesis, details available in the projects/WSN directory.
