SMAMID SWAN - Salt Wireless Accelerometric Network - a MEMS technology based WSN Wireless Sensor Arrangement
Strago started its activity in 1981 in the field in relation to geognostics and geophysical investigations, applied all the more in courteous engineering fields. The Company gradually expanded its difference in re activity all through structural diagnostics, instrumentation watchful eye, archaeological investigations, explosive clearance, buffer state decontamination and environmental superintendence, and inter alia by producing the specific measurement instruments for static and dynamic structural testing. Strago's expansion is the ascertainment respecting a continuous Research and Nurturing activities carried out with the support regarding as all get-out conditional personnel. Throughout the years we have managed a considerable number of projects entry Italy and askew, which have enabled us to globalize the training in connection with forces, thereby reaching the necessary flexibility linked into the plural in hand projects. The recent mass market introduction of MEMS (Micro Electro-mechanical Systems) has opened a vast bailiwick of studies and applications among various fields of engineering. MEMS study makes it cryptic to incorporate mechanical micrometer size - sensors, valves, gears, mirrors, actuators - in semiconductor yeoman, thus providing an interface electronic type for immediate use in a printed circuit board. The MEMS accelerometers Measurement Habit at Distributed Facility (SMAMID) is set up, in its body general form, by a network of autonomous of help units, each as to which incorporates an electronic circuit board of a MEMS accelerometer sensor, a processing unit and a communication system. SMAMID versatility enables its use inside different types of applications, such as: :: detection of movements; :: monitoring of vibration levels on areopagus moving vehicles; :: observance archway and shakes from passing vehicles; :: custody of the inclinations sustained over convenience conformable to objects and \ or buildings; :: detection of landslides on the rocky coasts. Each SMAMID Functional Unit (FU) consists as respects:‚¬ :: a triaxial MEMS accelerometer;‚¬ :: 8-bit microcontroller, which governs the activities of UF and processes command pulses;‚¬ :: 4 MiB speaking of mind for data storing;‚¬ :: a temperature sensor;‚¬ :: a clock \ calendar (regardless of a nullifier battery "button type"), which allows so that label the acquisitions with temporal informations;‚¬ :: RS485 miracle play communication interface;‚¬ :: wireless communication interface.‚¬ main applications<\p>
