Abstract:
-The study aims to prove that the designed sensor node can function as an independent system capable of providing energy for itself by harvesting the available Radio-Frequency energies and converting them to usable DC power. It is also an aim to transmit the sensor readings wirelessly at specified time intervals. In achieving these, several factors were considered. They include proper harvest-antenna positioning with respect to the source, appropriate capacitance and number of RF-to-DC converter stages, suitable energy-storage system, good implementation of data transmission system, and pertinent rate at which the readings are sent per day. Surveying at different times of the day was also done in order to determine the behaviour of the strength of the received RF energy. From the RF emissions of the GSM base station located inside the university, the gathered energy was proven to be enough in powering and allowing the wireless temperature and humidity sensor system to transmit data readings, thus making it autonomous.
