M18 Capacitive Proximity Sensor

Postby Priyanshi » Thu Apr 12, 2018 1:37 pm

Hey, is the sensor compatible with arduino? Some said that an external circuit may be needed to connect it with arduino. Can you help me with the circuit and also with it's code with arduino?

Hi Priyanshi,

Yes it is compatible with Arduino You can refer to the M18 Capacitive Proximity Sensor Wiring Diagram

Operating voltage: DC10-30V
Output signal: NPN, digital

Since Arduino IO pins is 5V, you can make connection something like this.

Then read digital signal at pin 9.

Hope this helps. Thanks.
