 If you are looking for Arduino 4-20mA Current loop receiver shield to connect 4-20mA sensor with your Arduino then you are at the right place. has a number of 4-20mA current loop receiver board for arduino. These arduino 4-20mA current loop shield has on board 16V power supply which can be used to power up the sensors and read their values. This 4-20mA current receiver shield can be used in industrial automation projects as well. You can pair it with relay board and control devices based on 4-20mA current loop receiver readings. This is an industrial grade high accuracy Arduino 4-20mA current loop receiver shield for arduino which works with all the arduino boards. To make the connections easy you can use this 4-20mA current Loop shield with arduino I²C shields.

Why Choose NCD?

With NCD you know you have a proven reliable, easy to use, and extensible product. This means you don’t have to spend valuable time researching how to jig-saw pieces of your project together to get them to work cohesively. Being manufactured in the U.S.A. you know you’ll get good support and a quality product. NCD also ensures you won’t have to put any time into soldering or building a PCB, just pick your boards and they click together. Just knowing that every sensor, relay controller, and component is built around the same concept will save you guess work on how well chips will integrate together. NCD really does make automation easy.

How it Works

Our idea is simple. Pick a platform. Get an adapter for that platform (usually less than $2). Connect any of our boards to that platform. That’s it. Hardware…done. All that’s left is some code to work for your specific application. To help with that we have an ever expanding bag of libraries and code samples.

We don’t add our own proprietary APIs to make things more complicated. You can just communicate to the relay like it was built into your platform.

About I²C

I²C is a high speed communication bus popular in electronic monitoring and control applications.

As it pertains to our devices you only need to worry about sending and receiving data. Each platform/language has its own library for communicating over I²C that will greatly simplify you application. Once you have that library imported you can start reading and writing data in a few minutes using our libraries and code samples as a basis.

IoT or Embedded?

Many people ask us if they can use these in an IoT application or if they’re just for embedded local applications. The answer is either. It’s really up to what your application calls for and what platform you’re going to use.

IoT Options

Many of our supported platforms have easy IoT integration on third party clouds. These give you a simple way to get your sensor data to anywhere and everywhere you need it around the globe.

Here are a few of our favorite cloud ready platforms:

  • Particle (easy to use cloud, excellent web IDE, wifi or cellular comms)
  • Onion Omega (built on linux, quick cloud connectivity) 
  • Raspberry Pi (powerful platform, clouds: Blink, IFTTT, Azure)

Local or Embedded?

Really any platform can be used for local embedded applications.

Here’s a few of our favorites:

  • Arduino (proven platform, simple coding)
  • Raspberry Pi (power platform, choose your own coding language)
