Abstract

The invention provides a capacitive sensor comprising a sensor conductor with a large guard conductor behind it, in which the sensitivity to distant objects is enhanced by minimising the area of conductive material forming the sensor conductor particularly in vertical strips representing the path of water over the sensor. Sensitivity to trickles of water such as from rain that flow over the sensor is thereby reduced.
