Wireless Humidity &Temperature SenSpot™ sensors offer a cutting-edge solution for real-time and long-term monitoring of structural temperature and humidity. Utilizing Resensys’s proprietary sensing, scheduling, and ultra-low power synchronization technology, these sensors provide a reliable and maintenance-free solution for up to a decade.
The wireless humidity and temperature sensor can be easily installed to monitor temperature and humidity around structural elements of bridges, buildings, and other infrastructures. This remote temperature and humidity sensor ensures no need for calibration, battery replacement, or any other maintenance during its entire service life. The measurement probe can extend the data point to even inside and inaccessible areas of a structure, with customizable probe lengths up to 200 feet.
