Without electric power on site, only electro valves with latching solenoid can be used, since this type can be operated by battery power. To operate a latching solenoid an irrigation controller is compulsory, since it creates the electrical impulse, which opens and closes the valve. Many battery operated irrigation controllers are equipped with a sensor port for soil moisture based automation.
