Hybrid solar and piezoelectric power supply system for iot environments

V magistrski nalogi predstavljamo metode za pridobivanje energije iz okolja in postopke za pretvorbo v električno energijo. Podrobno predstavljamo zgradbo, lastnosti, delovanje in uporabo piezoelektričnih senzorjev v te namene za uporabo v sistemih IoT. V nalogi smo razvili sistem za učinkovito pridobivanje energije iz okolja, z uporabo sončnih celic in piezoelektričnih senzorjev, s katerimi lahko energijo, ustvarjeno med kolesarjenjem, pretvorimo v električno energijo. Z vključitvijo sončnih celic smo razvili hibridni napajalni sistem za napajanje mobilnega senzorskega sistema, s povezljivostjo za pametna mesta, ki ga lahko namestimo na kolo. Tu služi za merjenje okolijskih parametrov, kot so temperatura, vlaga, vsebnost ogljikovega dioksida in hlapljivih organskih spojin kjerkoli v pametnem mestu.In this master\u27s thesis, we present methods for obtaining energy from the environment and procedures for transforming the energy into electric power. We detail the structure, properties, operation and use of piezoelectric sensors for use in the IOT systems. In the thesis we also developed a system for efficient energy harvesting from the environment using solar cells and piezoelectric sensors, which can produce energy during cycling, and can be converted into electric power. Together with solar cells, we have developed a hybrid power supply system for powering a mobile sensor system with a connectivity for smart cities that can be installed on the bicycle, and serves to measure environmental parameters such as temperature, humidity, carbon dioxide and organic compounds anywhere in the smart city
