Keywords: Sensor, communications, control, temperature, actuator


The system contains units: wireless, control, actuator, software equipment. RF wireless unit ensures wireless communication between control unit and sensors as well as wireless switch unit. The control unit controls system operation, i.e. communication transfer, sensor data processing as well as switching of actuator unit. Actuator switch unit is wireless controlled by control unit. There were hardware and software realized and tested in the designed system. The system was designed to operate with different type of physical sensors. The system can used PC, PDA or mobile phone to communication as well as signal processing. The control unit is the basic part, securing communication with the user by means of the display and keyboard. The unit communicates with wireless temperature sensors and wireless switch units. Second part of the system is represented by the wireless temperature sensors. The sensors measure temperature periodically and convey the measured data to the control unit. The third part is the wireless actuator units. The units communicate with the control unit. The main part is the control microprocessor, through which all remaining parts of the system are connected. The run of the system is supported by the control programs.
