Abstract

Domestic garden irrigation often constitutes a considerable percentage of the total urban scheme water demand. Improvements in irrigation efficiency have the potential to contribute to substantial water savings within the community. Improper scheduling of irrigation systems is one of the key factors contributing to inefficient use of water in domestic irrigation systems. The application of soil moisture sensors that automate irrigation cycles can help negate the effects of poor scheduling which would otherwise lead to over irrigation, resulting in the wastage of water resources and other consequential environmental impacts. A low-cost capacitance soil moisture sensor has been developed and is currently the subject of a twelve month trial at the Environmental Technology Centre, Murdoch University, Perth, Western Australia. The sensor is being assessed to determine its ability to contribute to water savings when used with shrub sprinklers, microspray and drip line irrigation on sandy soils, in the Mediterranean type climate that Perth experiences.
