IRROMETER SOIL MOISTURE SENSOR AND INTERFACE MODULE FOR BATTERY CONTROLLERS

Designed for home owners and using the proven WATERMARK sensor, this simple device “controls the controller” so that watering is only allowed when necessary based on soil moisture status. One sensor and an adjustment range designed specifically for turf grass make this an affordable and simple way to make any controller with “sensor” terminals a Smart controller.

The Battery WEM is designed for use with battery powered DC controllers that have a sensor circuit, functioning similarly to our standard WEM used with AC controllers.

Whenever a controller powers a valve, the WEM will either allow or prevent the irrigation based on soil moisture conditions. If the soil moisture is wetter than the setting selected on the WEM dial, an irrigation will be prevented. If the soil moisture is drier than the setting, the irrigation will be allowed.

Depending on the controller being used, either a closed or open switch position will be required to allow irrigation. The Battery WEM can be wired to accommodate either controller requirement, by selecting the appropriate switch connection wire pair.

Features:

• Simple to install on new or existing systems
• Easy to adjust
• Only allows watering if the sensing area actually requires water
• Four selectable moisture levels cover the range required for turf grass
• No need to re-program controllers for different seasons
• Pays for itself in water savings
