Can the AirGradient ONE be used outdoors? It is not recommended to use the AirGradient ONE outdoors. The enclosure is designed for indoor use with multiple mounting options: attachable clip-on stands for desktops, or wall mounts that perfectly fit typical US and EU junction boxes with a discreet cable management design. To ensure accurate temperature and humidity measurements, the AirGradient ONE features a dedicated sensor that is physically isolated from other mainboard components to prevent interference from the heat they generate. For outdoor use, the AirGradient Open Air is recommended. It is specifically designed with a robust, weather-proof enclosure and wall or pole mounting options, ensuring convenient outdoor installation and readiness for exposure to the elements.
