Wireless Enhanced Strain Gauge IoT SenSpot™

Description

The Resensys IoT sensor is versatile and provides an easy and inexpensive way to install a scalable solution for distributed structural integrity monitoring. It can measure two separate strain gauges. The transceiver and the solar panel can be easily mounted with either flanges or adhesive, both attached to the outer box. The device comes with a high-capacity lithium-ion battery charged by a solar panel. It does not require battery replacement making it is almost maintenance free. The whole product meets IP68 standard (completely weatherproof). As a result, it is an excellent choice for strain monitoring applications that require the sensors to be outside or in other hard to reach places.

The device needs a Nano SIM card with an active plan that supports 4G LTE and a good cellular coverage to periodically connect to a remote server and send all measured data through the cellular network. It is a completely stand-alone product and does not need any other intermediate device such as a gateway.

The strain gauge is designed by default to be attached on steel surfaces, but it can be easily customized for other surface types such as concrete or wood.

IoT sensors can be applied easily to as many critical spots on a structure as needed with minimal installation effort.

This is a completely stand-alone device. It measures, saves, and later sends data through a cellular network to the remote server. With this device, there is no need to use an expensive extra cellular gateway for sending the data. This significantly reduces the project overall cost especially for small projects where only a couple of sensors are needed.

This product uses Resensys’s proprietary Active RF Technology. Resensys SenSpot™ technology offers a high-performance method for large-scale sensing and ultra-energy efficient wireless communication.
