Touch/capacitive sensor for use in automation projects in e.g. house, has gate terminal connected to pad to detect microvolt variations, where variations are returned to MOSFET driver, and current is passed from storage device towards load

摘要

The sensor has a solar cell that is connected to an energy storage device i.e. micro-battery or lithium battery. A positive terminal is provided in the energy storage device. A MOSFET transistor is arranged with a drain terminal that is connected to a terminal of the energy storage device through a load. A terminal of a gate is connected to a touch pad for detection of microvolt variations generated due to touching of the finger on the touch pad. The variations are returned to a MOSFET driver, and current is passed from the energy storage device towards a circuit load i.e. generator. An independent claim is also included for a remote control.
