WiFi AC Current Monitor for Azure®

NCD set out to build the world’s best WiFi AC Current Monitor for Microsoft® Azure®. In doing so, NCD now incorporates a precision Split Core AC Current Monitoring Sensor with WiFi communications directly to Azure®. This current monitor makes it easy to monitor AC current and receive alerts when the AC current value exceeds the preset limits. 

NCD’s WiFi AC Current Monitor samples current at a high data rate and calculates the RMS value. Immediately after, the data is transmitted to the Azure cloud. Once connected to Azure, the AC current data can be streamed and monitored via WiFi. 

This IoT WiFi AC Current Monitor for Azure® was developed to work with the Microsoft® Azure® Cloud. As one of the world’s most popular IoT platforms, Azure® is an essential tool for monitoring NCD wireless sensor devices. 

When it comes to AC current monitoring, nothing compares to the ease of use, low price, high accuracy, operational temperature range, or security features offered at NCD. Note that this device will need to be externally powered and is capable of using a 6-32VDC power supply.

To begin, access the product setup guide under resources to learn how to use Azure® and NCD’s WiFi AC Current Monitor in conjunction.

Monitor AC Current with Microsoft® Azure® Cloud Shell

Microsoft® Azure® is a IoT cloud computing platform that allows for effortless data streaming through a built in cloud shell feature. 

Cloud shell is used for data streaming in an easy to read format. Furthermore, aspects of sensor data and how it is received is customizable in the Device Twin section. 

A user friendly guide on how to setup NCD’s WiFi AC Current Monitor is provided under the Resources Tab. This guide will cover how to setup the sensor and use the basic testing function on Azure®. Azure has more to offer so explore the IoT platform and learn how to creatively visualize sensor data. 

NCD’s WiFi AC Current Monitor for Azure® automatically reports AC Current data samples straight to the Azure® cloud. For many industries, IoT sensors with direct access to cloud platforms bring tremendous value at low installation costs with no hidden 3rd party fees or monthly services outside of the Azure platform.


  • Wireless AC Current Monitoring
  • Industrial Current Monitoring
  • Pump, Motor,Generators Electrical Behavior Analysis
  • Current Abnormality detection
  • Handheld Current monitoring equipment
  • Key component of predictive maintenance


This device supports:

  • WPA/WPA2/WPA2-Enterprise WiFi Security Protocols
  • IEEE-802.11B/G/N WiFi Protocols
  • DHCP or Static IP Managed Wireless Networks
Note: This device operates on MQTTS Protocol. 

Web Interface for Sensor Configuration

Upon connecting to the WiFi Sensor for use with Azure®, a Web Interface will automatically appear on screen. This Web Interface is where the settings can be configured for the  sensor. Settings such as preferred WiFi Network, Passwords, Device to Cloud Topic, and Azure Account Credentials are found here. 

Data Visualization

Azure® does provide methods of visualizing data for a cost. Charts, tables, and graphs are among the basic tools Microsoft® Azure® offers. Check out Azure® and look for the service called Stream Analytics Job. This service helps visualize sensor data on Azure® for a usage charge. 

Transmission Interval

This device sends data periodically based on user-preset timing intervals. As this sensor does not use batteries, the user does not need to adjust the transmission interval with the intention to save battery life. 


Not for use in outdoor applications or for use in excessive temperature conditions. This sensor has a minimum current draw requirement on the circuit being monitored of 1.5 amp. Prolonged exposure to extreme humidity conditions may damage this device. The sensing element is rated for use for 5 years and may be replaced. Electronics environmental operating range is -40°C to 85°C. NCD Warranty does not cover use in excessively smoky environments under any circumstances.

This device supports:

  • WPA/WPA2/WPA2-Enterprise WiFi Security Protocols
  • IEEE-802.11B/G/N WiFi Protocols
  • DHCP or Static IP Managed Wireless Networks

We Customize Just for You!!

NCD offers many custom IoT electronic design services to help tailor our product to your exact needs.  Whether you are looking for custom firmware, circuit board modifications, metal enclosures, or industrial color printing, we can help you with a wide variety of design services.

Custom IoT Electronic Design Services Process

Most of our users purchase off-the-shelf hardware for initial testing.  Once everything is working, they contact us to build a custom solution which may include specialized changes to the board, firmware, connectors, etc.  Custom boards have many advantages such as reduced wiring, easy installation, small size, less power consumption, and in some cases, an overall reduction in product cost.  Custom IoT Electronic Design Services will have your company name and logo on the board as well as the enclosure.

Customized IoT Electronics

NCD engineers can help build a customized solution for your particular application based on the designs you see on our website.  We can combine devices onto a single board, change the shape, or even some of the components to meet your exact needs.  We also provide turn-key metal enclosures with powder coating and full-color printing on the top side starting at just $500 for setup!  We have more than 20 years of experience in electronics design and manufacturing.  All of our products are designed and manufactured in the USA, so we are here to support the products we make.  We only ask that our customers prototype their needs using our existing products before we customize.

Customization Guidelines

  • Custom designs should be based on our existing product because we can’t build rockets or electric cars over here!
  • We do not provide customization services if it involves the introduction of a new or untested technology.
  • Custom engineering fees depend on your requirements, so please contact us for a quote!
  • We maintain ownership of all designs, including our customized designs as they are based on our existing Design.
  • We will only ship the customized product to you or your authorized agents.
  • We have an NDA available if needed.
  • The turn-around time is about 2-3 weeks.
  • We specialize in low-volume designs, no quantity is too small!
  • We have the ability to scale to large volumes as needed.

Getting Started with Product Customization

All you have to do is contact us and we will walk you through the process from beginning to end, based on your individual needs.  Some people are surprised at how fast we finish CAD design (usually a few hours), but keep in mind, we still have to build your design, which takes considerably more time.  When we customize product, here are the general services we provide:

  • We design the circuit board.
  • We communicate with our customers throughout the customization and manufacturing process.
  • We manufacture surface mount stencils and circuit boards.
  • We program our pick and place machines to build your boards.
  • We build a working sample and run it through our wave solder machine.
  • We test your custom IoT solution.
  • Once the design is finalized it won’t be possible to make changes during production (changes cost money and require us to repeat the above processes)
  • Once it meets all your requirements, we will start production as needed.
  • We work with our metal fabricators to design a metal enclosure if required.
  • You work with our artist to print the top side of the enclosure in full color with your company logo if required.

+MORE App customizations

We partnered with Blynk who have developed the +MORE app.  If you are interested in customization to their +MORE app then we're sure you will enjoy working with them as much as we did.  They can customize the user interface +MORE mobile app at your request.

  • Add new functionality and features to the mobile applications and web dashboard
  • Change/ add data visualizations options
