Soil Sensor Cellular Transport + Cloud Interface

GroPoint™ CloudConnect is a power-effcient, 2-way cellular (GSM or CDMA) modem that eliminates the need for a data logger by automatically capturing data from connected SDI-12 sensors and uploading it to a cloud-based data repository. Data can be downloaded to work with it locally, or use our web-based GroPoint CloudInsight software to analyze and visualize your data, set up alerts, forward data to another destination, or confgure your remote CloudConnect devices and SDI-12 sensors.


  • Cloud-based management: Sensor configuration, data storage, custom algebraic equations, custom data formats and forwarding, control, analysis, alarm notifications (email, SMS), reporting and actions all done in the cloud.
  • Easy configuration: Configure with any device connected to the Internet via the web-based GroPoint CloudInsight. No custom programming or scripts required.
  • Automated updates: Updates to firmware and cloud-based application are automatic.
  • Reliable connection: CloudConnect verifies connection with cell network and server connection before data is sent. If no connection is available or if data reception is not confirmed, data is saved and sent the next scheduled transmission.

Can I use CloudConnect with non-GroPoint sensors?

Absolutely, this device is sensor agnostic. Up to 4 analog sensors, 62 SDI-12 sensors or 4 pulse counter (ex. tipping bucket rain gauge) sensors can be attached.

Is CloudConnect a logger or a modem?

It's both! It's not a traditional logger, in that instead of logging all data on the device itself (although it does that too for redundancy, by storing all data on an SD flash memory card) it uploads all data to the cloud, and sends it to the Internet destination of your choice. This can be third-party software, Google Sheets, a simple HTML or XML file, or our own CloudInsight web software. Data is uploaded on a schedule which you define.

How can I access the data captured by the device, analyze it, graph it, etc.?

All data captured from your sensors is automatically uploaded to the cloud (and forwarded to the destination of your choice). This provides several options for accessing the data, including third-party software, Google Sheets, a simple HTML or XML file, or our own CloudInsight web software.

Do I need to buy a subscription to the CloudInsight web service in order to access my data?

No, only if you wish to use it as a data repository and analysis tool. CloudInsight is also used as the interface to configure CloudConnect, and is provided at no charge for that purpose. If you wish to use other software to store and analyze your data, then you would just configure CloudConnect to forward all data to the destination of your choice via HTTP/HTTP or FTP protocol, and there is no subscription charge for CloudInsight. However, CloudInsight offers many valuable features which make it an excellent choice and worth looking into. Contact us for more information and a demo.

What does CloudInsight cost, and where can I get more details?

The CloudInsight web-based software is available on a subscription basis, so there's no upfront purchase cost. Some of it's features include:

  • Drag-and-drop customizable dashboard: Customizable dashboard lets each user configure what at-a-glance data to show and how. Drag-and-drop widgets, place them where you want and stretch to resize. Choose high-visibility single data values, line graphs, bar charts, fuel-gauge style graphs, 360° directional graphs and more, for any parameter your station is measuring.
  • Custom math functions: Ability to set up simple to complex algebraic math functions and logic “if” statements using any of the sensor measurements as variables and display the resulting calculate data as separate graphs and data tables.
  • Selectable calculations: Min/max, average, totalization, evapotranspiration, flow, dew point, wind chill, and conversion of raw data.
  • Web services: Integrate third party web services for enhanced data analysis.
  • Data output available in an XML, Excel, .CSV, and many other popular data formats.
  • Alarms: Automatic alerts from user defined alarm condition for any measurement or calculation can be sent via email or SMS.
  • Security: Three user access levels for configurations, data management interface, and visualization.
  • Responsive design: works great on smartphones, tablets and PCs.

What cellular service providers can be used with CloudConnect?

Virtually any cellular provider that offers 3G CDMA or GSM service can be used. This includes Rogers, Telus and Bell in Canada; AT&T, Verizon, Sprint and T-Mobile in the US, and many more.

Does it provide one-way or two-way cellular communications?

CloudConnect provides 2-way communications, allowing you do send new information to the device (such as a change to a sampling schedule). However, unlike typical 2-way cellular modems which are in full 2-way receive mode 100% of the time so they can send the data payload to attached devices instantly, CloudConnect waits in a very low-power idle (sleep) mode until it is scheduled to wake up and connect to the cloud to retrieve any new instructions that may have been sent since the last time it connected. There are pros and cons to this approach, but we think the pros far outweigh the cons:

  • Pro: power consumption is extremely low, reducing the demands on an autonomous power supply and maximizing the uptime when placed into a remote environment (it's very unlikely that a solar-charged battery would ever run out of juice).
  • Pro: you still get the 2-way communication ability to send data to the remote device while retrieving data from it.
  • Con: any information you send to the device won't immediately be processed. The next time the CloudConnect device wakes up to connect to the cloud, the data will be transferred. Therefore the delay between when you make a configuration change and when it takes effect will be up the the time interval you set for cloud connection. In almost all cases, this is not a problem.

Why is the current consumption so low? Most cellular modems I'm familiar with are extreme power hogs.

CloudConnect provides 2-way communications, allowing you do send new information to the device (such as a change to a sampling schedule). However, unlike typical 2-way cellular modems which are in full 2-way receive mode 100% of the time so they can send the data payload to attached devices instantly, CloudConnect waits in a very low-power idle (sleep) mode until it is scheduled to wake up and connect to the cloud to retrieve any new instructions that may have been sent since the last time it connected. Therefore it is (typically) consuming less that 2mA, 99.99% of the time, consuming 150mA while receiving data from attached sensors and storing it (a few seconds once per interval) and consuming 250mA when transmitting the data through the cellular network (a few seconds once per interval).

By contrast, typical 2-way cellular modems are always running in a "active" mode so they can respond to incoming transmissions, and consuming 60-100mA 99% of the time.

How difficult is it to set up and configure?

CloudConnect is extremely easy to set up. All configuration and programming of the remote Cell-Net is done online via the cloud-based Stevens-Connect. There are 3 steps:

  1. Connect sensors
  2. Connect to power source
  3. Configure data handling (frequency, redundancy, destination) with a simple online GUI

How do I configure the device, set sampling and upload schedules, etc.?

Our web-based software CloudInsight is provided at no charge for configuring your remote CloudConnect hardware. Control all aspects of the device including logging and reporting intervals and all analog, pulse and SD-12 sensors. Make changes at any time, even if the station is in low-power (sleep) mode—all changes made will be synced to the remote station when it next transmits.

So rather than travel to the site to reconfigure, you can do it from anywhere there's an Internet connection. Rather than writing code or scripts, use a simple graphical interface. Rather than installing an app or other software and requiring a specific computer, do it with any Internet-enabled device (smartphone, tablet, Mac or PC).

What happens if the data flow is interrupted by cellular communication issues? How do I get my data? Will the data be lost?

CloudConnect has built-in redundancy so that data never gets lost. CloudConnect verifies the connection with the cell network and server connection before the data is sent. If no connection is available or if data reception is not confirmed, data is saved and sent with the next scheduled transmission.

In fact, all data is saved on the SD card regardless of whether it is successfully sent or not, so if there is ever a problem with your storage location, you can always obtain the data by visiting the CloudConnect device, ejecting the SD card and inserting into your SD card reader, and copying the data manually.
