Sensor device for monitoring danger area of lawn mower, has electrode unit with two electrodes forming capacitor system, and signal generator, which delivers signal on former electrode for impinging capacitor system

摘要

The sensor device has an electrode unit with two electrodes (SE,E1,E2,E3,E4) forming a capacitor system, and a signal generator (G), which delivers a signal on the former electrode for impinging the capacitor system. The signal adjoining the latter electrode of the electrode unit together with the signal provided by the signal generator is indicative for an approach of an object to the electric field of the electrode unit. An independent claim is also included for a lawn mower with lawn mower housing.
