SenSpot™ Vibration Ultra-Low Power Precision Sensing & Wireless Communication General structural integrity monitoring (Bridges, buildings, dams, tunnels, levies, etc.) Features & Benefits  Long lifetime (battery life of 10 years)  Wireless communication (IEEE 802.15.4)  Lightweight, about 120 gr  Easy mounting o o Self-adhesive, no drilling is required (e.g. steel) Flange-mount, drilling is required (e.g. concrete) Quick installation, 1-2 minutes Adjustable sampling interval: 0-400 samples per second Resolution options: 0.1mg , 1.0mg Full range: adjustable ±2g, ±4g, or ±8g. Working temperature: -40 to +150°F (-40 to +65°C) Shock survival: 1000g, 0.1s, no damage to the electronics Long communication range: 0.62mile (1.0Km) free space Ingress Protection: IP65, weatherproof and protected against rain, snow, and UV exposure Small size: 1.96” x 1.96” x 1.34” Power source: replaceable lithium-ion battery SenSpot™ provides an easy to install, scalable solution for distributed structural integrity monitoring. SenSpot™ vibration uses Resensys’s accurate measurement, large-scale sensing, wireless synchronization, and ultra-energy efficient wireless communication. SenSpot™ is designed to operate maintenance-free for decades. After installation, SenSpot™ does not need calibration, battery replacement, or any other maintenance during its entire service life. 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 installation effort. SenSpot™ vibration can be used on different elements of a structure to monitor

SenSpot™ - Wireless Vibration Vibration SenSpot comes in either self-adhesive or flange-mount form factors. A general diagram of this unit is shown below. email: [email protected]
