RainPoint rain sensor

The RainPoint HCS012ARF is a precision rainfall sensor that provides real-time rain monitoring with an accuracy of ±0.1 mm and a measuring range of 0 to 9999 mm. The device reports data every 3 minutes and communicates wirelessly at a distance of up to 120 m, ensuring constant access to information. The compact design measuring 125 × 110 × 108 mm and its low weight (189 g) makes the device discreet and easy to install in the garden or property.

Accurate real-time rainfall measurement

The measuring mechanism with a newly designed rainwater tank automatically drains water, allowing continuous and reliable rainfall monitoring. The sensor records data in real time, and the user can switch between millimeters and inches. Thanks to the high measurement accuracy, you can be sure that every change in the weather will be recorded, making it easier to plan watering or gardening.

Convenient access to data in the application

The device works with a mobile app, where you can check the amount of precipitation in real time. Data is displayed for different time periods - from the last hour, through 24 hours, to longer summaries and graphs. The intuitive interface allows you to quickly analyze rainfall history and better manage water in your garden or around your home.

Stable connection and hassle-free installation

The sensor uses wireless connectivity and works with a hub, ensuring stable data transmission at a distance of up to 120 m. Installation is simple – simply place the device on a flat surface in a horizontal position and ensure that it is stable, which directly affects the accuracy of measurements.

Thoughtful design and outdoor reliability

The device's housing is designed for outdoor use, and the waterproof construction protects the electronics from rain. The sensor also features a low battery indicator to help prevent unexpected interruptions. It is powered by 3 AA batteries (not included), allowing for flexible use without the need for wiring.

It is important to know

Before purchasing a RainPoint precision rain sensor, it is important to remember that it is an add-on to optimize your existing irrigation system, not a standalone solution. The biggest factors influencing your choice are compatibility with your water controller and the convenience of battery power depending on where you install it.

• The rain sensor is not a standalone controller – its effectiveness depends on being connected to an existing water controller.
• Battery power allows flexible use even where there is no access to an electrical outlet, but requires occasional battery replacement.
• When choosing, pay attention to compatibility with the currently installed system, as not all sensors are universally compatible.
• The sensor can significantly reduce unnecessary water consumption, but only if you properly integrate it into the schedule and operation of the system.

In practice

🟢 Automation of watering in case of rainfall

The sensor effectively connects to the programmer, detects rain and prevents unnecessary watering, making it very suitable for optimizing water consumption during unpredictable weather.

🟢 Adaptation in locations without electricity

The battery-powered design makes the product practical where there is no electrical outlet, such as in more remote garden areas.

🟡 Upgrading various existing systems

Use as an upgrade requires checking compatibility with current programmer; universal connectivity with all models is not guaranteed.

🟡 Battery maintenance and replacement

Battery power means the occasional need to replace batteries, which brings slightly more maintenance obligations compared to a mains-powered device.

Answers to frequently asked questions

What do I need besides this sensor for the system to work automatically?

You need a water controller to which the sensor connects – the product does not control watering on its own.

Is the sensor compatible with all programmers on the market?

No, please check if your programmer is compatible with this sensor model before purchasing.

Where is the best place to install the sensor?

It is recommended to install it in an open area where it will be exposed to precipitation, away from direct watering and protected from accidental damage.

How often will I need to replace the batteries?

The frequency of replacement depends on the intensity of use and the quality of the batteries, but on average, replacement is required once a year or according to the manufacturer's instructions.
