We proudly introduce the Ranos Indoor! This version of the Ranos is ideally suited for smart building applications. Information about noise levels is becoming increasingly interesting, while more and more building owners and users are installing a noise meter, in offices, for instance. In open-plan offices, people often work close together and are engaged in various tasks. Phone calls, hybrid meetings and Teams meetings all take place in the same space. The Ranos Indoor can help you gain insight into noise production in offices.
Objective measurement data
With these objective measurement data, improvements can be made, discussions can be conducted about too much noise in the department and the quality of quiet rooms can be monitored. The measurement data can be used as a security tool at times when the room is supposedly empty. Due to its wide measuring range, it can play an effective role in securing buildings.
The advantages of the Ranos Indoor at a glance:
- Very suitable for smart building applications;
- Obtain insights into the noise production in buildings, e.g. offices;
- Dynamic range of 33 – 121 dB and a DSP sample rate of 48 kHz;
- Implement improvements based on objective measurement data;
- Thanks to its wide measuring range, the Ranos Indoor can play an effective role in security;
- The housing is made of plastic and is dustproof;
- The Ranos Indoor communicates via LoRa;
- Data visualization via DSS data platform that seamlessly integrates with the Ranos dB;
- Easy to operate from any cloud platform.
If you use the Ranos dB Indoor, you will soon notice that the audio performances are very high. The Indoor has a dynamic range of 33 – 121 dB and a DSP sample rate of 48 kHz. It can be used for measuring the following units: LAeq, LCeq, dB (A) fast, dB (A) slow, dB (C) fast and dB (C) slow. The time weighting is fast, slow and Leq. Plus, the measurements interval can be customized via the app or the cloud.
Electret condenser microphone
The microphone of this indoor version is fixed in the housing and cannot be moved. The microphone type is an “electret condenser microphone” and the directivity is omni-directional.
The housing is made of plastic and is dustproof. The shape is designed to minimize reflections affecting the measurement signal being picked up by the microphone.
The indoor version is powered with a standard phone charger (5V DC USB-B).
The Ranos Indoor communicates via LoRa. We can deliver to all LoRa (frequency) regions in the world. The device is suitable for LoRaWAN Class C networks, allowing the cloud server to send direct and undelayed messages to the Ranos Indoor. This enables continuous adjustability of measurement settings, characteristics and network configurations.
Uplink and Downlink
As the Ranos Indoor can both send uplinks and receive downlinks, it is quite easy to operate from any cloud platform. Do you wish to set how often you receive certain measurements? No problem! You can also switch the GPS on and off. Refer to the DSS Connect App manual to find out exactly how this works and which settings are available.
DSS Connect App
You can connect the Ranos Indoor to your Android smartphone or tablet with the included USB cable. The Android app will open automatically. In the app, you can create an account and register the Ranos Indoor. The app recognizes the Indoor by its unique serial number. You can then enter the LoRa keys and send them to the device. The app itself checks whether the Ranos Indoor has the most recent firmware version installed and uploads and installs the firmware after you have given permission. For Class 1, the app is used to upload the FIR to the sensor in order to get a frequency response complying with IEC Standard Class 1 requirements.
DSS has its own data platform that integrates seamlessly with the Ranos Indoor. This is available for three months starting from the date of purchase. In addition, we offer an integration with Datacake and we can assist you in displaying the data in any desired IoT platform.
