I have this project where I will use an inductive proximity sensor and I need a bit long range to detect metallic objects and that is inductive proximity sensor. My question is how can I increase the range of the inductive proximity sensor? Thank youu
How can you adjust the range of a inductive proximity sensor? BADLY NEEDED AN ANSWER ASAP THANK YOUU
The sensor data sheet would have the details.
Check out metal detector circuits.
The area size of the sensor is one easy to control factor.
Reading the science and tech is a nice starting point.
Gotta try this one at the night club.

ALL the data sheets will tell you that ferrous material will be detected at a longer range than non-ferrous material. Beyond that testing will determine what is best for your project.

Define "a long range".

Hi,
Are you detecting teeth on a wheel or metal on a belt?
Can you please tell us your project details?
Thanks.. Tom....

My project is an automated trash bin that could detect metal waste such as can of soft drinks, staples, paper clips, and etc. using Arduino board
How is your testing going? Paperclips are steel, should be the best test for long range. Aluminum not so much. Do you have a design that ensures the material is always within range?
When will you show the program you are using and the test results?
Hi, @donutszzz
Have you purchased a sensor?
If so can you please post a link to spec/data?
What does the bin do if it detects metal?
You should be looking at hand held metal detectors.
Something like this is worth trying, not a lot of parts.
Google is your friend;
arduino handheld metal detector

Basically you can't.
I used a lot of these proximity sensors in my first job after leaving school in the late 1960s. And basically they are what they are.
Short of making your own sensor you are stuck with the range you have.
There are many types of inductive proximity sensors, a picture might have helped. But if you are trying to detect metallic objects may be take a loot in metal detector sensors
I also mean DIY. Metal Detector was one of the Radio Shack 80-in-1 projects I made work back in 1970 or 71 using basic components mounted on a cardboard surface with coil springs that I bent back to stick jumper wires into.
Close to the same was the Theremin Project.
If a middle-schooler with a circuit cookbook can do it...?
You could likely wrap a coil into the top of a plastic bin and detect metal as it is tossed in. Possibly with a servo/motor the item could be deflected to go out the side of the bin into another one.
Basically you bought a random sensor, asks if it'll do the job, hopes we will be psychics.
Was Tom vague in his request?
C'mon, you're wasting your and our time here.
That looks like it is the sort of proximity sensor I worked with.
As I said, there is nothing you can do to alter the range.
You cannot.
LOL, what does that cost?
It has a simple digital output, possibly with about 5 to 10mm range for industrial limit detecting.
Not for metal detecting to distinguish between material types.
Why don't you try the simple detector posted in post #11?
It uses minimal components and so quick to construct.
