Unfortunately the only options so far are to use an assortment of sensors to differentiate materials. As you mentioned the capacitive sensor is only capable of measuring the dielectric properties of a sensed material and reacting accordingly when a threshold is reached. An cluster of capacitive, inductive, optical (color and reflectivity, magnetic and other sensors is a good start but the property possibilities of materials are extremely wide.

@DorianMcIntire7 жыл бұрын
The types of sensor necessary will depend on the materials. Use an inductive sensor for metals and a capacitive sensor for non-metals. The difficult part is distinguishing between paper, plastic and other non-metal materials. I wold search for a sensor that can sense the dielectric proprieties of the material to help with that issue. Thanks for commenting.
@swastikmohapatra13827 жыл бұрын
Thanks for getting back to me. Capacitive sensors depend on the distance right? Which means the higher dielectric materials have a chance of getting detected at a greater distance than the smaller ones. Can I then use two sensors, one that detects plastic at a certain distance and rejects others and another one that accepts other kinds of waste? My main aim to is to separate bio and non biodegradable waste.
@DorianMcIntire7 жыл бұрын
Yes, Capacitive sensors can possibly determine material using distance, in controlled situations, but it would be very difficult to get consistent results. So much would depend on whether the material was wet or dry, thick or thin and other factors. I've noticed that many recycling faculties seem to focus on material handling methods to separate material on the fly. Properties such as material density (paper/non-paper), ferrous/non-ferrous are easy to separate and what remains typically will require special methods such as those you are proposing. The problem is not a simple one. Good luck.
@swastikmohapatra13827 жыл бұрын
I am already using an Inductive proximity for separating metals. I guess I can develop some system by connecting 3 Capacitive proximity sensors and then averaging the detection value(around 20-30 samples) for a wide range of materials. That would at least give me a threshold of the most common waste like plastics, paper, wood, food waste etc.

The output of the sensor is always digital (On/Off or 1/0) it is not an analog device so you cannot measure the dielectric properties directly. Getting a signal when the sensor is further provides an indirect indication of the dielectric properties. I would find another sensor, no doubt much more expensive, if I were you.
