Irrigation Sensors
Irrigation sensors are vitally important for reducing water wastage in any automated irrigation system. Especially in today’s climate, it is important that we don’t waste water in our gardens or anywhere for that matter. There’s nothing worse than neighbours or passers-by seeing your lawns and gardens watered by sprinklers when it’s raining — it looks bad and means water is being wasted. Rain sensors are the answer; simply wire them up to your irrigation controller and place the sensor on your roof guttering or a fence, and your garden will only be irrigated when it needs it.

At SunshowerOnline, we offer an extensive range of irrigation sensors for any application or climate. Each sensor type is engineered to optimise your water usage, giving you peace of mind and healthier landscapes. Our range includes:
Rain sensors are perfect for anyone seeking a straightforward solution to prevent irrigation during rainfall. They work by detecting moisture from rain and temporarily deactivating your sprinkler system until the area is sufficiently dried out. Our range includes wired and wireless rain sensors to fit your setup seamlessly.
Soil moisture sensors provide an irrigation controller with direct feedback from the ground. These sensor irrigation systems measure the moisture content in the soil and relay this data to your irrigation controller. By integrating soil moisture sensors, your system irrigates only when the soil moisture drops below a predefined threshold. The result? Healthier plants and minimal water waste.
These sensors are especially valuable for areas with varying soil types or gardens featuring diverse plants with unique watering needs. With SunshowerOnline’s soil moisture sensors, your garden will thrive, and your water bill will thank you.
Consider weather sensors for more comprehensive sensor input. Newer tech takes data from weather bureaus that cover a general area. These devices provide your controller with input from the actual weather at your property, which can be a very important differentiation. They monitor multiple environmental factors, including temperature, wind speed, humidity and rainfall. Using this data, they adjust irrigation schedules dynamically to match current weather conditions.
Weather sensors are perfect for large properties, commercial landscapes or gardens in regions with unpredictable climates. They ensure your irrigation system stays efficient, even during extreme weather variations.
Flow meters and flow sensors are the real game changers, offering fail-safe control and unparalleled insights into your water usage. These devices track the volume and rate of water flowing through your irrigation system. By detecting irregularities such as leaks or blockages, flow sensors help you address issues promptly, reducing water waste and preventing damage to your system.
At SunshowerOnline, we stock advanced flow sensors that integrate effortlessly with your irrigation controller. With real-time data at your fingertips, you can monitor, analyse and optimise your water usage like never before.

FAQs
What are irrigation sensors, and how do they work?
Irrigation system sensors are devices that monitor environmental conditions like rainfall, soil moisture, weather or water flow to optimise irrigation systems. They work by collecting real-time data and communicating with irrigation controllers to ensure water is used efficiently. This prevents overwatering, reduces waste and promotes healthier plants by irrigating only when necessary based on the sensor’s inputs.
What types of irrigation sensors are available?
Available irrigation sensors include:
- Rain sensors — Detect rainfall and pause irrigation during wet conditions.
- Soil moisture sensors — Measure soil hydration levels to water only when needed.
- Weather sensors — Monitor factors like temperature and humidity for precise irrigation.
- Flow meters and flow sensors — Track water usage, detect leaks and optimise system efficiency.
Each ensures water is used effectively and responsibly.
How do I choose the right irrigation sensor for my garden?
To choose the right irrigation system sensor, assess your garden’s needs. Use rain sensors to prevent watering during rain, soil moisture sensors for plants with specific hydration requirements and weather sensors for dynamic climate adjustments. Opt for flow meters and flow sensors to monitor water usage and detect leaks. Match the sensor type to your garden size, plant types and local weather conditions.
Can irrigation sensors help save water?
Yes, irrigation sensors help save water by ensuring your system irrigates only when necessary. Rain sensors pause watering during rainfall, soil moisture sensors prevent overwatering, weather sensors adjust schedules based on climate conditions and flow sensors detect leaks. By optimising water usage, these sensors reduce waste, lower water bills and promote sustainable gardening practices.
Are irrigation sensors compatible with all controllers?
Most irrigation sensors are compatible with popular controllers. But it’s important to note the some branded sensors work on a normally open circuit, and others normally closed. So you may find when mixing brands a sensor may inadvertently with with the inverse functionality! In that case it will still work, it just needs to be wired slightly differently.
How do I install a rain or soil moisture sensor?
Installation involves mounting the sensor in an open area (for rain) or at root level (for soil moisture), and connecting it to your controller using the sensor terminals. But importantly, always follow the included instructions.
My rain sensor is not shutting off the irrigation system, what should I check?
Rain Sensors are very uncomplicated devices, and failure is highly unusual. Check the sensor’s placement and ensure it’s exposed to rainfall. Inspect wiring connections, clean the sensor, and verify that the controller is set to recognise sensor input.
What are the benefits of using a flow sensor in my irrigation system?
Flow sensors are an exccelent addition to any compatible controller. They monitor water usage and detect leaks or line breaks by measuring the flow rate. They help prevent water waste and can trigger system alerts if abnormal flow is detected.
Does SunshowerOnline offer support and warranty for irrigation sensors?
Yes, all sensors are backed by manufacturer warranties and our expert support team, who can assist with product selection, installation, troubleshooting, and ongoing care.
