The ERS2 CO2 is a wireless LoRaWAN sensor for indoor use that measures CO2 levels, temperature, humidity, light, and motion. Its Scandinavian design makes it unobtrusive in business, public, and private environments.

The ERS2 CO2 is low-maintenance thanks to its long battery life, and the batteries can be easily replaced when needed. Sensor configurations, such as sampling rate, data rate, encryption key, triggers, activation, and more, can be quickly adjusted via NFC with a smartphone or through downlink.

A traffic light function indicates when a specific threshold for CO2 levels or another value has been reached. The threshold is configurable, and you can choose the color of the light, the frequency, and the light intensity.
