Indoor Ambient Temperature Node

Overview

The rpr-IoT-AT01 is a battery powered ambient temperature sensor node that communicates using long range radio compatible with LoRaWAN and the Things Network.

Data is stored on The RPR WeatherFile.com cloud for long-term storage and access. Readings can also be accessed by or sent in real time to your IoT dashboard of choice.

Applications

The rpr-IoT-AT01 has a wide range of applications where ambient temperature must be monitored. • Building energy management • Goods storage • Warehousing • Working conditions • Food Production • Personnel safety and comfort • Education and research projects • Sports halls • Museums • Agriculture and Horticulture
