CST ELF Flow Sensors

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.

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.

​​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.

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.

Fully installed by a professional, a domestic irrigation system will come out to about $1000 per zone. And as a DIY project, it can look more like $300 per zone! But of course that’s a very rough estimate, each system is different and there are a lot of factors to consider. Thankfully, we have the only tool around that INSTANTLY give an accurate estimate for your. Try our INSTANT Irrigation Quote Tool here!

To choose the right irrigation system, consider the size and layout of your garden or lawn, the types of plants you’re watering and your water source. Spray systems are ideal for most applications like lawns and gardens, while drip irrigation works well for mulched garden beds and areas exposed to wind and evaporation.

To set up an irrigation system, start by planning the layout, then install the mainline pipes, valves and fittings. Attach the sprinklers, drip emitters or other irrigation devices, and connect the system to a controller. Finally, test and adjust the system to check for proper coverage and efficiency.
