THE PRESENT INVENTION RELATES TO A WIRELESS SENSOR SYSTEM THAT POWERED BY THE HARVESTING OF AMBIENT ENERGY SUCH AS WIND, SOLAR, THERMAL, VIBRATION OR RADIO FREQUENCY (RF). THE ENERGY HARVESTERS GENERATE ELECTRICAL POWER FOR USE IN INDIVIDUAL SENSOR MOTES (1), THUS ELIMINATING THE NEED TO DELIVER POWER TO EACH SENSOR MOTE FROM A CENTRAL SOURCE. THE SENSOR MOTES (1) COMPRISE OF SENSORS (10) THAT GENERATE DATA SIGNALS BASED ON VARIOUS ENVIRONMENTAL PARAMETERS MEASURED, AS WELL AS WIRELESS TRANSMITTERS (50) THAT SEND THE DATA SIGNALS CONTAINING THE SENSOR MEASUREMENTS TO A ROUTER (120) LOCATED IN THE VICINITY. THE ROUTERS (120) ARE ALSO POWERED BY LARGER CAPACITY ENERGY HARVESTERS (140). THE ROUTERS (120) ACT AS WIRELESS RELAYS AND FURTHER TRANSMIT THE DATA SIGNALS TO A COLLECTOR (130).
