Wireless sensors

Wireless sensors

The series 3000 Transponders can capture differen analog and digital data and transfer them wirelessly. Wireless sensor networks can therefore be built fast and easily based on the Value-ID system 3000. Fields of application are energy and building technology where doors and windows can be monitored and temperatures can be measured and transfered wirelessly or in supermarkets where the cold chain can be monitored fully automatic and with little installation effort.


With little effort the Transponders are installed at the relevant positions by gluing or screwing. They permanently capture and transfer theyr data and transfer them to a management system. Each Transponder can be identified uniquely by its serial number. Alternatively or in addition the measurement data can be stored in the internal memory of the Transponder and read out at a later point in time.

Robust and reliable

The Value-ID active RFID systemworks reliably in harsh environments. Even close to liquids and metallic surfaces, where passive RFID systems fail, the Value-ID system delivers reliable reading performance.


A great variety of up to data interface options is available: RS232, USB or Ethernet. This allowas interfacing to virtually any management system. The optional use of power over ethernet simplifies installation and reduces investment cost. Integration of the Value-ID equipment in solutions for parking management, facility management and access control can be accomplished with little effort.

Integrated intelligence

The series 3000 Readers can optionally be operated in Stand- Alone mode. This means that the application logic runs inside of the device. This way, the access to doors or car barriers can be checked easily. The access rigths can be assigned by a Whitelist which is integrated in the Reader.

Optionally the Reader can be equipped with an Input/Output module providing two Relay outputs and two Opto-coupler inputs. This allows direct control of physical barriers.


Multiple Readers can be operated side by side without any negative interference.

Energy efficient

With an energy consumption of only 0,25W the Value-ID active RFID system operates extremely power saving.


The Transponders and Readers have an integrated AES-standard encryption which can be enabled optionally. Thus it is impossible to eavesdrop the user data or to manipulate data transmission.

Over The Air Kommunikation

Over The Air communication

A unique feature of the Value-ID Reader 3000 is its „Over The Air (OTA)“ communication ability. The RF interface will be used for communication between readers in this case. A gateway Reader will provide a virtual connection between a PC and a remote Reader. This way it is possible to install Readers without expensive and time consuming installation of network cables.

Investment protection

IT systems must meet theyr requirements also in the future. Thus the Operating System of the Reader (the “Firmware”) of all System 3000 Readers is updateable. The Firmware Upgrade is done using the standard communication interface or simply “Over The Air”. So it is not necessary to unmunt a Reader for doing a Firmware update. A special safety mechanism maintains an operable state of the Reader even if communication during update is being interrupted or if a power failure occurs.
