In-Situ Sensing of Surface and Atmospheric Moisture

Water is one of the most important materials on the Earth, being necessary for all forms of agriculture and many industrial processes. Water is also a critical element of many crop diseases and the prime cause of corrosion, rot and decay. The monitoring of atmospheric and surface water contributes to the understanding of these adverse effects and can be used to mitigate them. Sensors for both atmospheric and surface moisture have been in use for a long time but it is only recently that miniaturised and cheap sensors have become available so that in-situ, multi-point monitoring of water is feasible.
