The idea to make such a sensor logically follows from the development of the design of the "Portable Microwave Radiation Detector". I intend to attach it there as a removable component. This somewhat complicates the design (and also somewhat simplifies it).
Of the advantages - this allows you to take the sensor out to any reasonable distance, about 10 meters. Of course, using an adapter cable. This will allow you to hang several sensors on visualization and archiving systems (HMI), using common APCS equipment.
