In this paper, we implement a geospatial sensor network for monitoring a green technology stormwater runoff site. The sensor network uses OpenWRT, an embedded Linux operating system, and other open source software, to create a modified router for reading Maxim's 1-Wire™ protocol, queuing and transferring standardized sensor data while enabling location and time. The modified router created the bridge between the sensor protocols and the middle-level software to provide reliable data to both the sewer district and the Environmental Protection Agency. Representational State Transfer (REST) is used in the design philosophy of the client and server open source software for transferring the data from the embedded systems to the server level for storage and publication. The use of open source software not only creates a more affordable network but lowers the entry barrier to sensor networking and enables developers for continued innovation and standardization.
