LoRa Transmitter Sensor for Measuring Indoor Air
The Kube-Sky-RHT is a wireless transmitter designed for indoor use, specifically for monitoring temperature and humidity. Its clean and straightforward design makes it an attractive addition to places like office spaces.
This device employs LoRa technology, allowing it to provide extensive wireless radio coverage even when operating on batteries. It is commonly paired with the Nokeval Cell-Sky base station, but it can also be integrated into systems that utilise RS485 Modbus RTU.
The temperature and humidity transmitter looks great in offices and uses advanced technology to work wirelessly over long distances, either with its base station or other systems that use RS485 Modbus RTU.
Features and Specifications
The storage temperature range for this wireless device is from -30 to +60 °C, and it should be stored in a non-condensing environment. It can operate within a temperature range of 0 to +60 °C and in humidity conditions ranging from 0 to 100% RH without condensation.
The indoor air transmitter has an IP20 protection class and is constructed from plastic material (PC+ABS). The device’s dimensions are 95 mm x 75 mm x 27 mm, with an additional 1 mm for wall mounting, and it weighs 130 grams when equipped with batteries.
Speaking of batteries, it uses 2 pieces of LR6 (AA 1.5 V alkaline) batteries and typically has a battery life of around 10 years with default settings. To achieve this estimated battery life, it’s advisable to use high-quality batteries such as Energizer EN91.

What is a Wireless Temperature and Humidity Transmitter?
A wireless temperature and humidity transmitter is a device that measures and sends data about the temperature and humidity levels in its surroundings without the need for physical wires or connections.
This transmitter typically includes sensors to detect and quantify the temperature and humidity of the environment it’s placed in. Once the measurements are taken, the transmitter uses wireless communication technology to transmit this data to a receiver or central monitoring system.
These devices are commonly used in various applications, such as weather monitoring, home automation, industrial processes, and HVAC (Heating, Ventilation, and Air Conditioning) systems.
They provide real-time information about the conditions in a specific location, allowing for remote monitoring and control. Wi-Fi temperature and humidity transmitters are especially valuable in situations where running wires for data transmission would be impractical or inconvenient.
