Abstract
The present invention provides a measuring sensor (30) for measuring the presence of liquid having a relatively low electrical resistance (of the order of 0-1000 OMEGA ) comprising one or more conductors with high electrical resistance (of the order of 100 k OMEGA or more) which are maintained between connecting contacts on a carrier element made of synthetic material, cardboard or paper and which has a substantially meandering shape, wherein the resistance between the connecting contacts is notably reduced in the presence of the conducting liquid.
