Wireless Humidity and Temperature SenSpot™ Sensor


Wireless Humidity & Temperatue SenSpot™ sensor offers a breakthrough technology for real-time and long-term structural health monitoring. SenSpot™ uses Resensys’s proprietary sensing, scheduling and ultra-low power synchronization technology. SenSpot™ is designed to operate maintenance-free for more than a decade. After installation, SenSpot™ does not need calibration, battery replacement, or any other maintenance during its entire service life. Humidity and Temperature SenSpot™ sensor can be easily installed to monitor temperature and humidity around structural elements of bridges, buildings, etc.
