Connect NCD IoT Long Range Wireless Sensors to Google Cloud IoT using the Google IoT Gateway. Google Cloud IoT is one of the world’s most popular IoT platforms, so connectivity of the NCD ecosystem of IoT wireless sensors remains a top priority for our engineering team.

The NCD Google IoT Gateway connects NCD Wireless Sensors directly to Google® Cloud IoT® with an average setup time of about 5 minutes.  The NCD Google IoT Gateway listens for sensor data from NCD Wireless Sensors up to 2 miles away and converts the incoming data into JSON strings with real-world human-readable values.  Use the Google IoT Gateway to quickly and easily measure temperature directly on the Google® IoT cloud.  Send humidity data, current measurements for power consumption, light level data, counter data, and much more.  The NCD Google IoT Gateway is compatible with the entire NCD Enterprise product line of wireless sensors.  The Google IoT Gateway user interface supports up to 10 sensors while in configuration mode, displaying the signal strength and sensor data for each sensor during setup.  In Run mode (daily use), the Google IoT Gateway will work with as many sensors as memory will allow (estimated to be greater than 20, but we did not set a hard limit).  The Google IoT Gateway may also be used for configuration of basic settings of remote sensors.  Learn more about Google® Cloud IoT Core® here.

What Frequency Do I Need?

During purchase, you will see three frequency options.  Not all options are legal for use in all areas, so it’s important to make the right selection during purchase.  We will build your product and accessories based on the options chosen.  Here, we will explain these options in much greater detail, but please check your local laws BEFORE purchase.

900MHz for North America (U.S., Canada, and Mexico)

If you are located in North America, the 900MHz Option will provide the longest range currently supported with the best penetration through walls, buildings, industrial equipment, and trees.  This option is also the best choice for long range applications.  The official Line of Sight rating for this option is 2 Miles with included antennas or 28 Miles with high-gain antennas.  We suggest contacting for a high-gain antenna recommendation if required.  Please check your local laws before choosing this option.

868MHz for Europe Only

If you are located in Europe, the 868MHz Option is the longest range choice available at this time. This option offers better penetration through walls, buildings, trees, and industrial equipment than 2.4GHz. The official line of site rating for this option is 14.5km using 2.1dBi antennas. Please check your local laws before choosing this option.

2.4Ghz for Worldwide Use

The 2.4GHz option should be chosen if 900MHz and 868MHz are not legal for use in your country.  This option is now certified for use worldwide, including Europe, United States, Japan, Australia, Brazil, and South Korea. Please check your local laws before choosing this option just in case 2.4GHz is not legal in your area.

Not Sure?

If you are unsure of which sensor option to choose, please contact us.  We may be able to help determine which sensors are legal for use in your area.

Google IoT Gateway Configuration Pages

The Google IoT Gateway includes a embedded web page configuration screen that makes setup easy, simply register the gateway with your WiFi router by selecting the network name and entering your password, enter the region your project is configured for, the name of the Google Cloud IoT Registry, and upload the credentials JSON file for your Service account:

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.
