In this paper we present two different energy harvesting circuits for solar powered autonomous sensors.Both circuits are able to supply several types of sensor nodes. Performance of these circuits under different light conditions and different loads have been evaluated by experimental results conducted on implemented prototypes.Moreover, starting from the estimated working conditions of the sensor in terms of power requirements and light irradiance, the comparison between these circuits provides useful insights to help a designer in choosing of the optimal harvesting implementation.

Abstract
In this paper we present two different energy harvesting circuits for solar powered autonomous sensors.Both circuits are able to supply several types of sensor nodes. Performance of these circuits under different light conditions and different loads have been evaluated by experimental results conducted on implemented prototypes.Moreover, starting from the estimated working conditions of the sensor in terms of power requirements and light irradiance, the comparison between these circuits provides useful insights to help a designer in choosing of the optimal harvesting implementation.
