Wireless Smart-Emitter for Irrigation valves

Extreme Range Wireless Smart-Emitter for Sprinklers Valves

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 15+km (10+ mi.) distance 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 (1 m length) to connect to the the valve and digital inputs. These wires are passing 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.

The vast majority of the irrigation valve suppliers offer DC latching solenoids as a retrofit for their AC valves for applications where the irrigation controller is powered by batteries. Such retrofit solenoid is usually low cost (10-15US$).

With its ultra-low-power consumption, the STREGA wireless Smart-Emitter can operate on batteries during 5+ years* (calculation based on two irrigation periods/day) and through extreme long distances from the gateway/concentrator. LoRaWAN technology provides an exceptional obstacles penetration even in urban or sub-urban areas.

An external power source like a micro solar panel can also power the emitter for unlimited time operation.

The STREGA wireless Smart-Emitter permits to forget laying cables from the irrigation controller to the valve and offers a unique identification key combined with full encrypted wireless data for secure Open/Close control.

Extreme range transmission up to 15+ km (10+ mi) is achieved even if emitter is burried below ground surface

The cost of the STREGA wireless Smart-Emitter is far less expensive than the cost to dig and bury wires. It is more cost effective to replace buried wire systems with a wireless solution than to continuously repair wires that have been chewed by varmints or damaged by earth moving equipment.

And we have decided to offer more than super long range wireless connectivity to your valves: with its embedded real time clock and processing capability, the STREGA wireless Smart-Emitter can store your scheduled watering programs and open/close the valve by its own, without requiring to communicate with the irrigation controller ! It can even stop waterizing if a certain flow has been detected or on any abnormal alarm condition… directly at valve station level.

* battery life is subject to Open/Close frequency and Rx/Tx transmission frequency
