The rpr-IoT-SR01 is a battery powered Solar Radiation sensor node suitable for use with the EKO ML01 Si Pyranometer. It communicates using long range radio compatible with LoRaWAN and the Things Network. The low power electronics are housed in a rugged IP67 enclosure suitable for outdoor and industrial applications. A sealed connector is used for the connection to the sensor.

Data is stored on the rpr-IoT cloud and or the RPR WeatherFile.com cloud for long-term storage and access. Readings and status information is displayed on the rpr-IoT dashboard (subscription required for enhanced features). The dashboard enables data from several nodes to be plotted and displayed in a flexible manner to suit the user.
The unit uses a long life 4000mAh A size Lithium Thionyl Chloride (LiSOCl2) battery which is user replaceable.
