SenSpot™ strain gauge uses Resensys’s accurate measurement, large-scale sensing, wireless synchronization, and ultra-energy efficient wireless communication. SenSpot™ is designed to operate maintenance-free for more than a decade. SenSpot™ does not need calibration, battery replacement, or other maintenance after installation. Due to small size and lightweight, adhesive-mount SenSpot™ sensors can be applied easily to as many critical spots on a structure as needed, with minimal installati
