Abstract:
The realized system for wireless measurement of temperature in the many different places is described. The paper describes a new architecture of a multisensor system for remote temperature measurement using wireless communications. The system is composed of temperature sensors with digital output. The system ensures RF wireless data transfer, wireless communication between control unit and sensors as well as wireless switch unit. The integrated RF chip nRF9E5 ensures wireless communication. The control unit controls communications, sensor data processing as well as switching of actuator unit. The control unit contains main control microprocessor ATMEL as well as wireless communication unit. The actuator switch unit communicates with control unit using RF wireless way. Partial control programmes were designed for wireless unit control. There are many program functions implemented. The control software of the whole system has been designed. The designed system, i.e. hardware and softwa
re has been realized and tested. The system can operated in the range of 300 m in the free space. The number of sensor can be extensible. The system can be use to operate with different type of sensor, i.e. for measurement other type of quantities. PDA or mobile phone can be used to communication with control unit.
