Carbon Dioxide Air Quality Transmitter/Controller Sensor
The Kube-Sky-RHT-CO2 is a wireless transmitter designed for monitoring indoor temperature, humidity, and carbon dioxide levels. Its sleek and minimalist design makes it an attractive addition to environments such as office spaces.
This transmitter utilises LoRa technology, providing extensive radio coverage for wireless battery-operated devices over long distances. While it is commonly paired with the Nokeval Sky-radio base station, it is also compatible with integration into systems using RS485 Modbus RTU.
Features and Specifications
The CO2 sensor can be safely stored within a temperature range of -30 to +60°C without the risk of condensation. The wireless carbon dioxide transmitter is designed to operate efficiently in temperatures ranging from 0 to +60°C and can function in humidity levels ranging from 0 to 100% relative humidity without condensation.
The sensor boasts a protection rating of IP20 and is constructed with a plastic enclosure made from PC+ABS material. The unit’s dimensions measure 95 mm x 75 mm x 47 mm, with an additional 1 mm for wall mounting.
When equipped with batteries, the device weighs 160 grams and requires 2 LR6 batteries (AA 1.5V alkaline) for power. Under default settings, the internal batteries typically last for 4 years, but to optimise battery life, it is recommended to use high-quality batteries like Energizer EN91.

What is a CO2 Sensor?
A CO2 sensor, or carbon dioxide sensor, is a device that detects and measures the concentration of carbon dioxide gas in the surrounding environment. It’s commonly used in various applications, including indoor air quality monitoring and climate control systems.
