What is Spherag?

Spherag is a manufacturer of solar-powered smart irrigation controllers and precision sensors, designed to digitise and automate irrigation for agricultural growers of all scales. Its flagship product line — the Atlas controller — connects directly to mobile networks using a built-in SIM card, enabling full remote management of valves, pumps, and sensors from any device, anywhere.

Plug in. Power on. Farm smarter. 

Spherag is specifically designed for the challenges of agriculture: remote locations, unpredictable weather, and no time for complicated installations. Every unit comes ready to use: Mount the control unit, connect your valves and sensors and your system will be up and running in just a few minutes.

Solar-powered autonomy 
Every Atlas system is self-sufficient thanks to solar energy. No power connection, no electrician, no infrastructure requirements. All you have to do is install the solar panel, and the system will then power itself indefinitely.

Built-in cellular modem 
The Atlas controller includes an integrated SIM card and cellular modem that operates across all major 2G/4G/5G networks. No Wi-Fi, external antennas, or repeaters needed — ideal for remote agricultural sites.

Manage from anywhere 
Control valves, adjust schedules, and view live sensor data from your smartphone or desktop. Receive instant alerts by SMS, push notification, or email the moment something needs your attention.
Atlas controller 

The brain of your irrigation system 

The Spherag Atlas is a solar-powered irrigation controller built to handle the complexity of modern agricultural water management. It connects to any existing irrigation infrastructure, supports a wide range of sensors, and gives you full programmatic control — all from a single compact, weatherproof unit. 

Designed to withstand dust, moisture, and vibration in outdoor environments, Atlas is equally at home in a polytunnel corner or a fully exposed arable field. 

  • Supports up to 8 valve outputs and 8 water meters or switches 
  • Integrated 2G/4G/5G cellular modem with dedicated SIM card 
  • Compatible with soil, weather, pressure, and level sensors 
  • Schedule irrigation by time, volume, or live sensor data 
  • Encrypted communication — dedicated per-device SIM, not shared 
  • Subscription includes 1 year mobile & server connectivity 
  • Compact, dust- and moisture-resistant outdoor enclosure

Built for growers

Spherag is suited to a wide range of crops and farming operations. Whether you manage a single field or a network of sites, the system scales with you.

Arable crops

Precision irrigation for potatoes, onions, and cereals — schedule by volume or soil moisture trigger to match each crop's exact water demand at every growth stage.

Soft fruit & berry farms

Real-time soil moisture and tensiometer data helps raspberry, blueberry, and strawberry growers avoid crop water stress during critical flowering and fruiting periods.

Tree fruit orchards

Manage irrigation across apple and pear orchards with flexible valve outputs, frost protection scheduling, and automated weather-based adjustments.

Asparagus & brassicas

Tap into soil EC and temperature sensors to optimise irrigation windows and avoid waterlogging in sensitive vegetable crops grown in heavier soils.

Nurseries & tree production

Control multiple zones independently across container nursery areas or in-field tree production, with flexible scheduling and instant remote override.

Shared irrigation networks

Monitor and manage multi-farm or multi-field water distribution networks from a single dashboard, with individual reporting per site or zone.

Know what's happening — before it becomes a problem 

Spherag gives you a live view across your entire irrigation network. Access real-time readings from water meters, pressure sensors, soil sensors, and weather stations at any time — from any device. Monitor tank and well levels, track flow rates, and download comprehensive reports at the push of a button.

Alerts — sent the moment something happens 
Spherag detects and notifies you immediately about events like pipe leaks, overpressure, underpressure, tank overflow etc, via SMS, push notification, or email — your choice.

What you can monitor in real time 
  • Water meter readings and cumulative flow volumes 
  • Pressure levels — detect overpressure and underpressure events 
  • Soil moisture, temperature, and electrical conductivity 
  • Tank and well water levels Weather station data — rainfall, wind, and evapotranspiration 
  • Valve and pump status — open, closed, or fault condition

Designed to leave less footprint, not less performance 

Spherag was built from the ground up with environmental impact in mind. Solar power eliminates the carbon cost of mains electricity on-site. Sensor-triggered irrigation eliminates the water waste of time-based schedules. And because every unit is cellular-connected, there's no need to lay cables or install infrastructure that disturbs soil and habitat. 

The system scales without complexity — whether you start with one Atlas unit and a single soil sensor, or deploy across a network of fields, the cloud platform grows with you. Adding zones, sensors, or users requires no new hardware at the hub level.

Frequently Asked Questions

Spherag is a smart irrigation technology brand that turns conventional irrigation systems into connected, data-driven networks. Its solar-powered controllers, soil sensors, and tensiometers allow farmers and growers to monitor and automate irrigation remotely — based on real-time soil, weather, and water data — all managed through a secure cloud-based app. The flagship product, the Atlas controller, is available in the UK through Bosta.
No. Spherag's Atlas controllers include an integrated cellular modem with a dedicated SIM card, connecting directly to 2G/4G mobile networks. There's no need for Wi-Fi, broadband, cables, or external antennas. This makes Spherag particularly well suited to remote agricultural sites where internet infrastructure is unavailable or unreliable.
All Spherag field devices are solar-powered. They operate entirely independently of mains electricity, which means they can be deployed anywhere on a farm without infrastructure work, trenching, or cable runs. This significantly reduces installation time and cost, especially for remote or multi-field deployments.
Spherag is designed as a plug-and-play system. Units can be installed quickly on-site without specialist electrical knowledge. Mount the solar panel, connect your existing valves and sensors, and the unit connects automatically to the Spherag cloud platform. Bosta's irrigation team — Louise Miller and Madison Howes — can advise on system design, sensor placement, and zoning to match your specific farm layout and crop type.
Each Atlas unit supports up to 8 valve outputs and 8 water meters or switches. It is compatible with a broad range of sensors, including the Sentek soil moisture and EC probe, stainless steel tensiometers, air temperature and humidity sensors, pressure sensors, flow meters, and weather stations. All sensor data is viewable in real time through the Spherag cloud platform.
Yes. The Spherag cloud platform gives you full remote access via a smartphone app or web browser. You can adjust irrigation schedules, switch individual valves on or off, review historical data, and monitor live sensor readings from any location. The system also sends instant alerts via SMS, push notification, or email if it detects leaks, pressure anomalies, pump faults, or other system events — so you can act quickly without needing to visit the field.
Spherag is designed for a wide range of agricultural applications, including arable crops (potatoes, onions, brassicas), tree fruit (apples, pears), soft fruit (raspberries, blueberries, strawberries), asparagus, nursery stock, and trees. It is equally suitable for small holdings, large-scale arable farms, and shared irrigation networks spanning multiple fields or sites.
Spherag products are available to order online through Bosta UK, with delivery across Great Britain. Bosta's irrigation specialists Louise and Madison can help with product selection, system design, and ongoing technical support. The product range includes the Atlas solar controller (2-station and higher configurations), the Sentek 10 + EC soil sensor, stainless steel tensiometers, and air temperature and humidity sensors.
