Kube-Sky-RHT-PIDVOC – Nokeval

This is a LoRa transmitter for indoor air measurements. This model includes temperature, relative humidity and VOC gases (TVOC) measuring sensors. It sends the measurements wireless through a LoRa signal to receiver and the Ovaport web service monitoring system.

Q2 2019

The Kube-Sky-RHT-PIDVOC has a LoRa output signal based Nokeval Sky radio with a very long range for indoor air quality measurements. The Kube-Sky-RHT-PIDVOC includes temperature, relative humidity and TVOC measuring sensors. Because of its nice and clean design the Kube series are ideal for indoor applications and more clean environments, such as measuring the temperature, the relative humidity and the VOC gases in for example offices, musea, schools, laboratories and warehouses.

The model with -PIDVOC suffix has a high quality photoionization detector for detecting volatile organic compounds. The sensor is factory calibrated for isobutylene and it can operate in a continuous exposure unlike many sensors that will auto-zero themselves. The sensitivity goes to tens of ppb. This model must be powered with an external supply. The LoRa signal is an advanced modulation technique that allows much longer range than the traditional techniques. The Nokeval OVASKY family uses this technology at the license-free 433 MHz ISM band (not available in all countries). The battery powered 10 mW transmitters have an open-space range of more than 5 kilometers and the pratical range is 30 to 300 meters in most indoor applications. The modulation technique tolerates other traffic on the same band quite well.
