Our hardware design objective is to produce large quantities of low-cost sensors which work together to track water flow and water quality in real time. We have been able to take advantage of low-cost commercial off the shelf (COTS) sensors and the wide availability of cell phone data networks to produce a very capable aquatic sensor at extremely low cost. Our current generation of floating sensors is the result of four years of experimentation and research.
Capabilities
1. Use GPS to track surface water flow
2. Can use differential drive motors to move to a desired GPS point at approximately 0.5 m/s
3. Can send flow and quality data in real time using GSM network (like an iPhone using 3G)
4. Can use buoyancy control system to "dive" to 5m depth.
5. Can communicate with each other over Zigbee short range wireless radio.
6. Can measure salinity in real time
7. 72 hour operational lifetime
