Soil moisture sensor (SMS) controllers measure soil moisture content where it is most vital to plants – the active root zone.
A properly working SMS controller does not stress plants or decrease turfgrass quality because it allows the irrigation system to apply the amount of water needed to meet plant water requirements.
A soil moisture sensor can be used in place of a conventional rain sensor. Compare them to decide which is best for you?
To take full advantage of the water-savings offered by the use of a soil moisture sensor system, a variance that allows irrigation during otherwise restricted irrigation windows is required. SMS variances for locations within the City of Tampa water service area are provided by the Southwest Florida Water Management District.
