Latest Developments in TRWS Sensors

Since 2000, MPS System has been continuously advancing the hardware and software of TRWS weighing rain sensors. The introduction of powerful new hardware enables the integration of comprehensive algorithms, significantly improving measurement accuracy by mitigating the influence of factors like wind and temperature changes and gives more accurate measurements. Customer feedback and additional requirements have been implemented into the firmware.

 Key innovations

• Bluetooth Communication and intuitive mobile application facilitates wireless operation, offering a user-friendly interface for device configuration, maintenance, accuracy testing, and firmware upgrades
• Instant 10-second rain intensity (PRinst) achieving an accuracy of nearly 98%, comparable to corresponding precipitation data
• Advanced heating modes: Configurable via the application, including proportional heating power adjustments based on ambient temperature
• Precipitation recording below standard thresholds
• Rain duration (PRdur) published in seconds as a registered data point alongside PRlast measurements

Evolution of Rain Detection Technology

In the early 2000s, a rain detector (RD) was integrated with the TRWS sensor. However, after extensive testing and comparisons, we opted to eliminate the RD and rely solely on the TRWS sensor for accurate rain duration data.

While traditional rain detector technologies (e.g., optical, contact, or capacitive) can detect raindrops, they come with several limitations:

• Additional installation and costs
• Detection of irrelevant events, such as hail or moisture condensation, which are not classified as rain
• Limited ability to detect solid precipitation accurately

Our approach measuring rain duration directly through the TRWS sensor eliminates these issues. This method provides more precise and reliable data using a single, integrated device.
