The core activity of Koalasense is the development and manufacture of autonomous, wireless sensors (called "Koalas") for monitoring environmental conditions, climate, and other parameters. These sensors are energy-efficient, cost-effective, and can be deployed in hard-to-reach locations without a power grid connection. The company also offers services such as software and hardware development, electronic circuit design, programming, and small-series manufacturing. The sensors can be monitored and configured via a web platform and mobile apps, and alarms can be set up for specific events.
