Using Inductive Proximity sensors with Arduino

Using Inductive Proximity sensors with Arduino

int limitSwitch = 13;
int state = LOW;
void setup() {

pinMode(limitSwitch,INPUT);

}

void loop() {

int val = digitalRead(limitSwitch);

if( val != state ){
state = val;

OMG - Just what I needed and how specific and clear, Thank you so much ;-)

The model number for your sensor ends in B. But I don't see any of those sensors on the internet that end in just B . They all seem to have a letter after the B, such as BX or B Y.

Thank you so much, this was just what I needed! Great video.

Hi, great video. But just a beginner question: Do i need the optokoppler also, if i use an NPN Sensor? I mean that if i use an NPN sensor and switch the digital input of the Arduino to INPUT_PULLUP --> Can i then directly connect the black signal cable to the digital input and remove R2 (because of the internal pullup)?

I have connected only one sensor on analog pin.all other analog pins are not connected to any sensor but when I read other analog pins I get the same reading on them how I can avoid this problem.plz suggest any solution.

[sanjaybatra]

is there any better circuit then this using internal PULLUP resistor ?

[cyriljourdan]

Great, thanks ! Just something I noticed, if I'm not mistaken Emitter and Collector are inverted on the first slide.

im wondering what the forward voltage on that optocoupler is to be able to wire 12v directly to it?

[shogunvanrepi]

if the supply voltage is 28 volts, will the output voltage remain stable at 5 volts through this circuit?

Thank you very much. A Liteon LTV-815 can be replaced with PC-817

[akhtar]

To the point explanation thankyou very much..subscribed

Hi can I connect it direct into the arduino without resistors if I use 5V proxmity sensor?

[denisdarii]

Hi, please tell me, how can i use an optocoupler with mechanical limit switches.

[akashagale]

What is the switching frequency of the inductive proximity sensor

[kennybos]

Can I use 9Vin directly to the Inductive Sensor then use 7805 IC to regulate the output to 5V the connect it to the analog?

[CJfoks]

Hi. Can this be used with other Type of NPN sensors like contrast sensors from SICK ?

[cody]

Hi, how can I make a servomotor rotate when I sense?

[priyanshubhagat]

Is there any way to make this project run as it is without using the optocoupler PC817

[Wegegta-]

the program didn't work in my project can u find my problem?

[freemusictribe]

What Power Supply should I use?
Is a 12V and 1A Power Supply enough?
