SenSpot™ Wireless 1D/3D Vibration Ultra-Low Power Precision Sensing & Wireless Communication Typical Applications ▪ Bridge health monitoring ▪ General structural integrity monitoring ings, dams, tunnels, levies, etc.) Man-made seismic effect monitoring Detection of vehicular or barge collision Features & Benefits ▪ Long lifetime (battery life of 10 years) ▪ Wireless communication (IEEE 802.15.4) ▪ Lightweight, about 120 grams ▪ Easy mounting ▪ Self-adhesive, no drilling is required Flange-mount, drilling is required (e.g., concrete) Shock survival: 1000g, 0.1s, no damage to the electronics Quick installation, 1-2 minutes Adjustable sampling interval: 50 to 500 samples per second (The lower range is customizable) Adjustable sensitivity threshold: From 8mg to 512mg. Threshold can also be set adaptive to limit number of events Small size: 50mm (1.96”) x 50mm (1.96”) x 34mm (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 proprietary Active RF Technology, similar to other SenSpot™ in its family. Resensys SenSpot™ technology offers a high-performance method for large-scale sensing, synchronization, and ultra-energy efficient wireless communication. Number of samples: two options • Normal or short waveform: 1024 samples per event • Long waveform: 4096 samples per event Adjustable Transmitting interval Full range: ±2g (“g” is the acceleration of gravity) Resolution: 4 ug 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 Noise Level: X & Y &Z Direction: Working temperature: -40°C to +65°C (-40 to +150°F) Long communication range: 1.0k

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 vibration. nation of Vibration SenSpot™ and Resensys Camera is a perfect solution for applications such as barge collision monitoring system. When a barge hits the bridge fenders, it vibrates the fender and SenSpot™ detects an event. At the same time, the camera takes a photo of the hitting barge. As a result, the entity that is in charge of the bridge...
