Rebates start at $35 per irrigation controller station.
A soil moisture sensor measures soil moisture content in the active root zone on your property. A measurement is taken before each scheduled irrigation event, and the irrigation controller bypasses the scheduled run cycle if the soil moisture is above a certain threshold level defined by the user. The sensor should be placed in a location that best represents the overall soil moisture condition of the site, and must be connected to an irrigation system controller that accepts a signal from the sensor. SoCal Water$mart eligible soil moisture sensor systems must include a sensor and a calibrator (these are typically packaged together in the same device) and an irrigation controller. A sensor/calibrator can be added to an existing compatible irrigation controller, however, it is not eligible for a rebate if the user already received a rebate for a Weather Based Irrigation Controller. Rebates are not available for both the Soil Moisture Sensor System and a Weather Based Irrigation Controller if purchased together.
