Cascoda KNX IoT Environmental Sensor Overview
The Cascoda KNX IoT Environment Sensor provides environment measurements compliant to the Indoor Environmental Quality (IEQ) provisions of the EU Energy Performance of Buildings Directive (EPBD). It is battery powered and includes a high-resolution E-Paper display and GUI users; installers; configuration settings & QR Code; and to show current environment values. The Environment Sensor has a build in Graphical User interface (GUI) menu. The front buttons are used to navigate between the different pages of the GUI.
The Cascoda KNX IoT Environment Sensor can be easily incorporated into KNX networks using the Cascoda KNX IoT HubTM available here.
