Need Suggestion regarding any good 4-20mA Proximity Sensors used to control wireless with arduino.
Also for controlling wireless 4-20mA sensors what hardware should i use ???
Interfacing 4-20 mA sensors is easy with Arduinos - do a search on this forum, it's been discussed many times, including circuits on how to convert the current into a voltage that the Arduino can read on it's analog pin.
4-20mA Current Loop receivers or normal 4-20mA Current receivers which one is better and what is difference in both device ?
4-20mA Current Loop receivers or normal 4-20mA Current
"4-20mA Current Loop" and "4-20mA Current" are, for practical purposes, synonymous.
Regards
the easiest way to do this by using a resistor.
You can checkout this tutorial on how to read 4-20mA using arduino
"read 4-20mA using arduino"
This link leads to a confusing product (technically correct); in my opinion a simple resistor sensing solution does for basic cases.
Best regards
