Wireless and batteryless sensor

This complete wireless sensing solution SA-D003 designed by SENSeOR is specifically tailored for surface temperature monitoring of critical equipments or industrial processes. The system has been developed in order to work where no other existing product works i.e. harsh environments, confined and/or inaccessible places – all this with almost unlimited autonomy. This maintenance-free SAW sensing device can be placed anywhere and can be easily moved from one place to another, for instance, when performing punctual diagnosis.

Unique competencies in antenna design and Surface Acoustic Wave (SAW) technology allow the high-tech firm to lead this revolutionary wireless and passive sensing solution for optimal customer value. The sensing device consists in a specific planar antenna (97x82x17cm3) together with a miniature SAW sensor (-20 to +160°C) operating passively, which is incorporated to the antenna. Data collection is then remotely performed (typically up to 3 meters) in real-time by the provided reader unit, which is connected to a computer (via USB, analog or even Zigbee link) for data visualization and storage. One of the key applications is temperature monitoring in high-voltage breaker boxes (harsh environment since subject to strong electromagnetic fields), where this wireless, passive, maintenance-free and cost effective solution is perfectly suited.
