The work is devoted to the review of application of wireless technologies for measurement of parameters of technological processes. Two types of wireless network architectures are considered: "star" and "cellular". It is proposed to take as a basis the topology "cellular scheme". Three wireless standards are given: ZigBee, Wi-Fi and Bluetooth. The advantage of ZigBee technology is shown. RFID technology is considered as the basis of the wireless sensor. Features of construction of system with its application are considered. The block diagram of the control system is given. Classification of RFID-tags is given. Examples of such sensors are given.

Keywords: wireless technologies, cellular circuit, RFID tags, wireless sensors, automation of technological processes
