Wireless low cost temperature and humidity sensors with PV microcells. Determination of design parameters by means of experimental measurements

The potential of cost efficiency of Zero Energy Buildings has not been tackled widely so far. The market of Zero Energy Buildings lacks reliable and cost effective data logging and measuring devices of energy parameters in Buildings. The research group at the Aerospace School of Madrid has addressed the gap by developing wireless sensors to enable energy-supply by means of PV microcells. The challenge for those devices consists of the need of sending data every minute without being affected by the lack of sun. The aim of this paper is to demonstrate by means of experimental data that the proposed device is continuously provided with Tension, so that it can send regular data over the years.
