Abstract: A modular sensing station architecture that supports flexible power management includes one or more sensors connected to a WINS node. Each node includes power supply, data acquisition, programmable microprocessor and wireless transceiver modules that communicate data and instructions over a bus. The bus suitably includes a signal bus for communicating instructions and low bandwidth data and a high-capacity data bus for transferring high bandwidth data and executing high power tasks. The dual bus approach provides constant communications among the modules and low-capacity data transfer with the option to activate the high-power circuits or tasks only as needed.
