Good Day Masters, I'm new to Arduino and I have a project that should detect metallic objects.
I bought an inductive sensor**(Omron E2E-X5ME1)**, and I would just want to ask for ideas, or sample calculation or sample code to detect if an object is metallic or not.
I really need it badly.
Thanks a lot in advance!
BTW this is the datasheet of the sensor
Sensing Distance: 5 mm
Supply Voltage: 24 V
Output Configuration: NPN
Maximum Output Current: 200 mA
Operating Supply Voltage: 12 V to 24 V
Output Voltage: 2 V
I wish someone could help me in installation and coding. Thanks alot. God Bless!
So this is a 3-wire sensor, ground, supply and an open-collector output (as far as I can see). I suggest powering it at 12V, and running a 1k resistor from its output to 5V rail.
Before connecting to Arduino check that the output switches from about 5V (no metal present) to about 0V (metal present) - any voltage higher than 5V means I'm wrong about its connection - don't connect it to Arduino!
