This paper describes a development stage of a 3D application developed using WebGL for reporting temperature, humidity, pressure and dew point from a sensor installed in a location where constant monitoring is required. The data from the sensor is stored in an Oracle database. The sensor measures the environmental parameters once per minute every day. The web pages that make the data available to Internet users are developed using Oracle APEX. The 3D model of the monitored location and the sensor were designed using Blender. The 3D models are loaded into the Oracle database and rendered, using WebGL, inside web pages.
