PRP-02 Professional Tipping Bucket Rain Gauge

The PRP-02 is a professional rain gauge sensor with a unique single spoon tipping bucket that is a reliable low cost high quality rain gauge ideal for small weather stations, rainfall measurement, irrigation/soil moisture management and drain water measurement in drip irrigation.

A very accurate and reliable automatic rain gauge, the bucket is made in POM which a more dismissive material and therefore makes dust and dirt not stick so easily on the spoon and maximizes water release. The outer shell is made from STYROSUN which makes the surface easy to clean and the PRP-02’s high quality plastic materials and a simple design make for a very long durability (10-20 years)

It also has only one adjustment screw which makes it easy to recalibrate. All PRP-02 Professional Rain Gauges are manually calibrated, which gives you the guarantee for a very accurate measurement. Accuracy: +/- 2%.

The electronic printed circuit board with individually tested and high quality reed switches protects against extreme weather conditions such as extreme frost or heat. This includes corrosion from salt water due to the PCB is coated with weather-­‐resistant varnish.



You can also use the PRP-02 sensor in a custom IoT system using a SNiP (Sensor-Node Integrated Package)


The SNiP-PRP is a ‘Sensor Node Integrated Package’ for LoRaWAN communication of real-time rainfall and precipitation measurements for continuous environmental monitoring.

The base SNiP-PRP integrates 1x PRP-02 with an AD-NODE to a site’s unique network, communication and power requirements.

Alternatively, the SNiP-WS24 integrates 1x MFR-NODE with three sensors: 1x ATMOS-14 Temp & Humidity Sensor, 1x ATMOS 22 Sonic Anemometer and 1x PRP-02 Professional Tipping Bucket Rain Gauge. The MFR-NODE can support 1 added Sensor. With the PRP-02 combined with the ATMOS-14 and ATMOS 22 sensors, multiple atmospheric parameters can all be continuously measured in real-time including: Wind Speed, Direction & Gust Speed, Air Temperature, Relative Humidity, Barometric Pressure and Vapour Pressure, as well as Rainfall and Precipitation.

The PRP-02 Professional Tipping Bucket Rain Gauge measures the precipitation by means of a funnel (orifice 50 cm2), which leads the water down into the single self-emptying tipping POM spoon, held in place by a hard ferrite magnet. The magnet always exerts just enough tension to allow the measuring spoon to empty in one quick movement (less than 300 ms) and then return to its normal position, ready to once again collect precipitation. This means the counter weight always remains the same opposite to other conventional two spoons tipping bucket rain gauges.
