Aranet is an environmental Internet of Things (IoT) temperature, humidity and CO2 monitoring solution. Aranet Mini is designed for smaller site-size applications, and Aranet Pro is for industrial-grade deployment. The solution consists of a base station and environmentally durable wireless sensors that can be placed outdoors and exposed to high levels of humidity. The sensors have low energy consumption, which allows them to function as long as 10 years without battery replacement. The base station can support as many as 100 sensors within at least a 3-km (1.9-mi) line-of-sight distance.
