Kit with wireless and batteryless sensors

This SAW-TDK1 demonstration kit from SENSeOR, the world specialist in SAW (Surface Acoustic Wave)-based sensing solutions operating wirelessly and without batteries, includes 3 wireless temperature sensors (-20 to +160°C), a reader unit and a visualization software. Incorporated in different types of appropriate packagings, tiny (only 5x5x1.5 mm3), robust and totally passive SAW sensing elements are connected to customized antennas. Thus they can be mounted in harsh environments (explosive and/or irradiated atmospheres) as well as in confined and/or inaccessible places (mobile and rotating machines, tanks, ovens, buried pipelines, incorporated in materials…) – all this with almost unlimited autonomy.

The reader unit remotely interrogates (typically up to 3 meters) in real-time SAW sensors within the ISM band at 434MHz. This reader unit connects to a computer (via USB, analog or even Zigbee link) for data visualization and storage. Once mounted, SAW sensors are maintenance-free and allow avoiding unwanted cables of wired sensors. Furthermore, the drawbacks related to the active electronics of conventional wireless sensors are bypassed.
