The system was designed for sensor measurement and data transfer. A new architecture of a multisensor system for temperature measurement using wireless communications was used in the paper. There are used sensors with digital or analog outputs . The control software of the system has been created. Different software were designed for wireless units. The integrated RF chip nRF9E5 was used as wireless units. Chip ensures wireless communication between control unit and sensors as well as wireless switch unit. The control unit controls system operation, i.e. communication, sensor data processing as well as work of actuator unit. Communication is ensured in the range of 300 m in the free space. The system was designed to operate with different type of sensors. The number of sensor can be variable. The system can used PC, PDA or mobile phone to communication with control unit .
