The STREGA wireless smart-emitter has been designed to provide a seamless ultra-long-range wireless capability to most common irrigation and sprinklers valves. This wireless smart-emitter device connects directly to the DC latching solenoid of the valve while providing wireless connectivity up to 10-plus miles from the control room or the irrigation controller even through obstacles. The STREGA wireless smart-emitter is provided within an IP68 enclosure with 6 wires to connect to the valve and digital inputs. These wires pass through a sealing gland to ensure complete waterproofing. Two extra digital inputs can be associated to the control of the valve for flow monitoring or any alarm status. With its ultra-low-power consumption, the STREGA wireless smart-emitter operates on batteries for 5-plus years (calculation based on two irrigation periods/day) and through extreme long distances from the gateway/concentrator. LoRaWAN technology provides exceptional obstacle penetration even in urban or suburban areas.
