This humidity sensor consists of 2 copper conductors that are located at small distance from each other. The relay switches as soon as the moisture makes a connection that is more or less electrically ...
The circuit shown in the figure measures relative humidity in air at the low temperatures found in applications like cold storage of food items and greenhouses. Instead of using electrical signal ...
Water molecules distort the electrical resistance of graphene, but a team of researchers has discovered that when this two-dimensional material is integrated with the metal of a circuit, contact ...
