Magic sensor. Autonomous sensor in a cup of tea. This long-lived sensor is powered solely by the changes in temperature it measures,requiring no battery. It is only active when there is a change to measure. Voltage is generated in its pyroelectric materials by changes in temperature. The voltage is converted into a radio signal transmitted by an antenna. This data can be picked up by a receiver up to 20 metres away. Similar sensors can be used to continuously check the pressure of vehicle tyres. The sensor was developed by Siemens,Munich-Perlach,Germany | |
