THERMOELECTRIC GENERATOR FOR SOIL SENSOR MOTE

The present invention provides a thermoelectric generator for soil sensor mote [20]. In the ambient energy harvester, a lens [32] and heat trap compartment [36] provides light concentration [40] which increases the temperature gradient between the ground layers and ground surface [26] of the earth?s soil which is detected by cold junction [22] and hot junction [24] respectively. A charge is developed and accumulated in the thermal element [40]. The harvested power is then transformed to electrical potential. The micro thermal energy harvester in the soil sensor mote [20] device shall replace the usage of batteries, works even in rain and dry spells seasons, eliminate maintenance drawback and improve the deployment in locality where human assistance is remote.
