The T-Rex is an automated intrusion detection system. Nodes continuously scan a coverage area using two MaxBotix LV-MaxSonar®-EZ4™ High Performance Sonar Range Finders and records the information (angular position and distance to object) in a CSV file. A master node pulls this data from the nodes, compiles it into a bitmap image, and compares the current data with the previous data pulled. If an intrusion is detected a warning is given.

The project was developed as modularly as possible, with each node being able to run autonomosly, with no input from the master node. This would make the addition of additional nodes a simple process. Each node is powered by an eBox and all software (both master and nodal) was written in C#.
