The Calsense soil moisture sensor is used to accurately measure the volumetric water content at the depth at which the sensor is placed, by measuring the dielectric constant of the soil using capacitance/frequency domain technology. It is used to maintain soil water balance for optimum plant growth and to manage the amount of irrigation water applied. The model CS-2W-MOIST is used in conjunction with the 2-Wire option, model CS3-2WIRE-OPT, offered only with the Calsense model CS3000 irrigation controller.

Easy to Install

  • Provides two measurements: soil moisture content and soil temperature
  • Small size makes it easy to install in the field and the robust sensor can be pushed directly into undisturbed soil to ensure good accuracy.
  • Signal filtering minimizes salinity and textural effects, making the CS-2W-MOIST accurate in most soils.

Resists Corrosion

  • Provides a soil moisture sensor and decoder in one for wiring one remote control valve
  • Built-in surge and lightning protection
  • Search for and identify all decoders connected to the controller on the 2-Wire and list them in the controller by serial number
  • Robust epoxy overmold to resist corrosive environments

Soil Moisture Sensor 2-Wire Decoder Details

The combination of sensor/decoder comes standard with a 16-foot cable for proper moisture sensor placement, and with the ability to wire one remote control valve to the 2-Wire cable. Moisture sensors can be installed anywhere on the 2-Wire path. Smart technology enables assigning decoder’s serial number associated with a specific moisture sensor location, to a group of like stations at the controller. The model CS3000 compares the sensor reading measured at the beginning of each irrigation cycle to the user-defined set point to determine when to stop irrigation.
