A SENSOR DEVICE WITH A TILT METER, WIRELESS COMMUNICATION FACILITY AND MAGNETIC FIXING

摘要

One embodiment of a sensor device comprises a housing containing a tilt meter and a wireless communication facility configured to transmit data from the tilt meter; and a fixing for attaching the housing to a surface to be monitored by the tilt meter. The fixing comprises a triangular configuration of first, second and third magnets for magnetically supporting the sensor device on the surface. The housing is attached onto the surface by the magnets for use of the tilt meter. The magnets are located substantially on the periphery of the fixing. The first and second magnets are spaced apart from one another in a substantially horizontal direction, and the third magnet is located vertically above or below and horizontally between said first and second magnets.
