Low-power wireless sensor node with ATMEGA328
Klvaňa, Jakub ; Pál, Tamás (referee) ; Krajsa, Ondřej (advisor)
The aim of this semestral thesis is to design low-power wireless sensor node, which will be used to measure temperature, humidity and pressure. The first part deals with the central unit, which will collect and process the measured data. The second part is devoted to design for a wireless node that is formed by ATMega328 microcontroller, three sensors (temperature, pressure and humidity), baterry which is charged by photovoltaic cell and the wireless module. Conclusion is a brief summary of this work and outlines follow-up procedure in dealing with the bachelor’s thesis.
