Product information

Air quality sensor accessories maximise the performance of our Kunak AIR stations.

Attached externally to the device, they collect and provide:

  • Meteorological and atmospheric information (wind direction and speed, precipitation, heat stress, solar radiation, UV-A ultraviolet radiation, etc.)
  • Energy independence, thanks to the internal battery with which the stations are equipped and the possibility of connecting a solar panel. The Kunak AIR units can also be connected to mains electricity.

These accessories for air quality sensors turn our solutions into all-terrain devices capable of monitoring atmospheric conditions in remote areas with no or irregular power supply.

The collection of meteorological variables also makes it possible to analyse the impact of the weather on the concentration or immission levels of various pollutants.

Kunak AIR stations are equipped with a rechargeable lithium battery which prevents the equipment from shutting down due to a power cut. In this way, they can continue working for long periods of time until the power is restored.

Different power packs are available to power the devices.

Solar panel

Solar panel

The high-efficiency monocrystalline solar panel is robust, waterproof (IP67) and has been designed for prolonged outdoor use in any environment. The photovoltaic panel makes the device autonomous from the power grid, allowing the installation anywhere without civil works or in remote locations. All solar panel models include a mounting kit.
