So it's not appropriate to add to this enumeration. \r\n\r\nThe reason for this field is to know what types of objects will reflect vs not reflect. Ultrasonic vs infrared have very different behaviour when looking at glass for example. \r\n\r\nAs mentioned, in that comment, lasers can have different types of radiation. We could consider adding VISIBLE and ULTRAVIOLET to complement the existing INFRARED definition. \r\n\r\nHowever I am not aware of a \"light\" based distance measuring device operating in the visible or ultraviolet frequencies. \r\n\r\nThere are also definitely microwave based sensors which might be applicable. However we try not to speculatively update messages until there is a clearly known use case. \r\n\r\nFrom what sensor or sensors are you trying to represent the data using this message format?"}}
