Automatic Waste Separator - School project 

Aluminium - Induction sensor - 6€ ,, PP plastic and glass - optic sensor (phototransistor or photodiode + IR LED ) connected on analog input ARDUINO and PC measuring...

Thank you...Any particular model for optic sensor you recommend? I want to purchase but not sure which model or brand to purchase (Digikey, Sparkfun, and Adafruit is where I want to purchase from)

optic sensor ---- (Phototransistor , InfraRED LED)

hello brother plz give ur mail id i want do this project i want this project in details so i want to know about the hardware part

Bro i want to do this project can u help me out

I use also arduino uno and dc motor for main conveyor and stepper motor for rotation conveyor

@@dominikcislak191 ok, I understand now. Thank you.

plastic and paper has different transparency of light, so you can test the transparency with other light : IR, normal light, laser, etc...

Yes + induction sensor

Thanks for your help...I watch the video again and again and I am enlighten now

@@bennymumoy7680 you can see that the glass is coloured - so it has low transparency, PP plastic has more transparency, and Plastic bottle has he highest transparency of IR light, Iron is separated with magnets, and aluminium has 0% transparency and detected by inductive sensors

@@bennymumoy7680 Could you pass me your contact email. raoofnaushad.7@gmail.com or mail me in this.

you can try it, but I think, that capacitive sensor detect only humidity..., I dont know if capacitive sensors have analog output to detect value of humidity

Atmega 328ppu - Arduino

+Dominik Čislák How many sensors you've used in this project?

IR LED, Normal LED , Induction sensor , it is only alpha version, I plan the whole remake , and use all the possibilities for detection of material properties , and optical camera, face detection and others. for example - Eddy current seperator - which can separate Alluminium,Cu / Ferrous materials ... detect deformation with deformation sensor on robotic arms... , audio tests , and more...

+Dominik Čislák I search for other sensors and they used capacitive proximity sensor to separate plastic, wood, glass etc.

yes , you can test it

induction sensor, optic sensor (phototransistor, different LED light)

how is that glass nd plastic separated.. can u pls tell me in detail.. i read all of ur comments even though i couldnt get tat.. im doing the same kind of project.. waste management.. i would be grateful if u could explain me

glass and plastic have different transparency..., you should try (phototransistor or photodiode, and different light, and proccess it via arduino, or any microcontroller, = analog sensing)

do u have the schematic..?

Shriya LS could you please pass me your contact email. I am doing the same project so i think you can help me please

I think - with capacitive proximity switch

i dont have circuit and mechanical diagrams, now i re-creating this works , i post there theory of separating materials...
