ABOUT THE RANOS ONE
The RANOS ONE is a fully wireless, solar-capable outdoor sound level meter designed for permanent or temporary noise monitoring. It operates autonomously without wired power or data connections and communicates via LoRaWAN. Measurement accuracy complies with IEC 61672-1:2014 Class 1 and has been validated by an accredited laboratory according to IEC 61672-3:2013.

The system is particularly suitable for locations without grid power, though wired power options are also supported.
It performs according to IEC 61672-1:2014 Class 1, the highest class of precision for sound level measurement instruments. This makes it suitable for regulatory-grade acoustic evidence.
IEC 61672-1:2014 is the international standard for sound level meters. Class 1 is the highest precision grade, defining strict tolerances for measurement accuracy across a wide frequency range. Instruments certified to this standard are accepted for regulatory compliance, legal evidence, and official environmental monitoring, making Class 1 the benchmark for professional noise measurement worldwide.
The RANOS ONE measures LAFast, LASlow, LAeq, LAFmin, LAFmax, and their C-weighted equivalents (LCFast, LCSlow, LCeq, LCFmin, LCFmax). Additional measurement quantities and weightings are available via USB or upon request for specific use cases.
The RANOS ONE includes an integrated sealed lead acid battery (6V, 12Ah) and a solar panel (9.4Wh) for fully autonomous operation. It can also be powered via 24VDC (circular connector) or USB-C Power Delivery.
Yes. The unit is rated IP54 for outdoor use. The microphone carries an IP57 rating with a Gore membrane for advanced ingress and moisture protection. The windscreen is weather and UV resistant with a water-repellent coating and integrated birdspike.
Via LoRaWAN (Class A) — supporting EU868, US915, AU923, and other regional frequencies. LoRa keys are pre-provisioned for Over-The-Air-Activation (OTAA), so the device is ready to connect to your network straight out of the box. Local real-time readings are also available via USB-C and the DSS ConnectAPP.
Yes. The RANOS ONE is CE marked, meaning it meets all applicable European health, safety, and environmental requirements. This confirms the device is compliant with EU regulations and ready for deployment across the European market, relevant for cities, industry, and integrators who require documented product compliance as part of their procurement or installation process.
Yes. The RANOS ONE includes GPS for accurate timestamps and positioning — important for both multi-node deployments and legally defensible data records.
No. The RANOS ONE ships plug-and-play with a pre-installed full battery, pre-configured LoRa keys, and pole and wall mount accessories included.
SOFTWARE & DATA
Through the DSS ConnectAPP, a web application accessible via Google Chrome or Opera at app.dutchsensorsystems.com. It offers simple configuration options and live local readings.
DSS Dashboard+ is the native cloud platform for the RANOS ONE. It provides graphs, event-based alerts, reporting, and our Noise Budget Prediction feature, which helps construction sites, event organizers, and industrial operators stay within daily noise limits and avoid fines.
Yes. The RANOS ONE uses standard LoRaWAN, making it compatible with most LoRaWAN network servers and IoT platforms. Please contact us to discuss your specific integration requirements.
APPLICATIONS & USE CASES
Our solutions are used by municipalities and smart cities, construction companies, industrial operators, event organizers, environmental consultants, researchers, and IoT integrators and resellers.
Noise is increasingly recognized as a public health issue by the WHO, the European Environment Agency, and national governments. Regulatory requirements are tightening, while communities demand greater transparency. Continuous, calibrated monitoring is no longer optional — it's becoming standard practice.
The RANOS ONE combined with Dashboard+ is particularly well-suited for construction environments where daily noise limits must be respected and documented. Read more on the Construction Noise page.
Yes. The RANOS ONE is designed for scalable network deployment. Dense measurement networks improve data resolution and reduce the risk of out-of-context readings caused by weather or local conditions.
PARTNERSHIP & RESELLING
Yes. DSS works with a global network of resellers, integrators, and is growing it's distributor network. If you're interested in partnering with us, please reach out via sales@dutchsensorsystems.com.
Yes. Demo units are available for authorized partners at a preferential rate, subject to our partner agreement terms.
Yes. The RANOS ONE is available in regional variants supporting different LoRaWAN frequency plans (EU868, US915, AU923, and others), making it deployable worldwide.
