Virtual Fields
Virtual Fields are an easy way to convert incoming data from your device into instantly meaningful quantities. A lot of sensors give their readings in voltage or current, for example, virtual fields provide the means to convert these into more useful values such as, speed, temperature, height etc. Also, this can provide us with more accurate results, for ex. when a sensor has 2 temperatures sensors, we can combine them for an average temperature.
