Siemens Mobility has introduced a new type of traffic detector based on magnetic sensors, which could provide an alternative to the conventional systems that have to be embedded under the road’s surface.

The Sitraffic Wimag system has fully wireless detectors and uses magnetic sensors, a processor, radio antenna and a battery to transmit detected events to a base station.

The sensor and base station are designed for a temperature range from –
45 to +80°C, with the base station capable of ensuring the radio link to a maximum of 48 sensors.
