MPWise - Multi Parameter wireless sensing system

MPwise system with Screen

The MP-wise is an innovative system that allow several kind of sensors to be combined witha highly performant computing system able to implement complex information integration andprocessing tasks at node (sensor) level and therefore suitable for a wide range of possible applications.The aim of the new multi hazard monitoring and early warning system is to fulfillthe needs for different types of application, mainly regional and on-site earthquake early warningand rapid response systems, structural health monitoring and site-effect estimation by twodimensionalarrays. However, it might be useful also for geotechnical problems like landslides monitoring, or other geohazards like tsunami. The system is designed in a modular way, allowing to design easily different configurations with respect to the used sensors and the communication interfaces depending on the the different application. Referring to the possible sensors,the prototype is capable to be instrumented (and was tested for the connection) with standard strong motion, weak motion sensor, broadband sensors, MEMS sensor including accelerometer and gyroscope, camera, temperature and humidity sensor and a low cost GNSS system.
