The RN320-CDT is a fully wireless sensor that supports LoRa communication, ideal for IoT, designed for use in high-precision workspaces like operating rooms where constant brightness is required, and exhibition halls and archives where the condition of records must be preserved. It features an e-paper display for immediate confirmation of measured values.

We've incorporated a compact light sensor that won't harm the exhibition environment. The RN320-CDT product manages indoor carbon dioxide concentration, light intensity, temperature, and humidity all in one. Because it consumes little power, once installed, there's no need to worry about maintenance until the sensor's calibration cycle. Furthermore, its battery-powered design makes installation and maintenance both easy and convenient.

A three-color LED (green: normal, orange: caution, red: warning) indicates the status, allowing you to immediately determine whether the measured carbon dioxide concentration is within the normal range or requires action. A built-in buzzer generates a powerful warning alarm with a decibel level comparable to that of a helicopter, making it ideal for ensuring safety on site.

The latest international communication protocol, LoRaWAN, has the advantage of supporting long-distance communication without additional repeaters while consuming less power. Taking full advantage of this, RN320 can transmit data up to 10km. RN320 can also transmit measurement data to the Cloud Serivce-based Radionode365 or to the user server.

The included 17000mAh battery provides up to five years of use when measuring at 30-minute intervals. It uses a Type-C battery, making battery replacement easy.

Are you still using a paper recorder or memory type recorder? Simply insert a micro SD card without any separate settings and data files will be saved by date. Files are saved in CSV format and files are created by day.

RN320 offers a total of 3 different installation methods. You can use a standing stand to freely move the product, and you can complete the installation by attaching the product to the place where it needs to be installed using a magnetic plate without drilling. If you need a more secure fixation, you can install the product using screws. Install it in the method that best suits your site.

The roller data logger RN320 is small in size (11.5 x 11.5 x 40mm) and weighs 360g including batter, making it convenient to use. It is designed to blend into the surrounding environment without a foreign feeling, not only when stored in showrooms and showcases, but also in general offices or manufacturing sites.
