Large projects in the heavy construction industry come with major risks. For example, millions of dollars-worth of concrete may be poured daily, and each of these pours must be carefully monitored to ensure the core and ambient temperatures are within tight specification ranges to ensure correct curing to prevent cracking and instability. Remote monitoring and automated reporting stand to revolutionize this industry with notifications that enable engineers to quickly remediate any issues.
Watch our recorded webinar to learn how Wake, Inc. developed HardTrack, a solution for heavy civil construction projects. Utilizing Digi Connect Sensor+ and Digi Remote Manager, HardTrack monitors each concrete pour and provides data via dashboards and notifications to help teams keep tabs on their projects and proactively solve issues – in the office or in the field – potentially saving millions of dollars in remediation costs.

Thank you again for attending our session on IoT Solutions for Heavy Civil Construction. Here are the questions that followed the presentation and their answers. If you have additional questions, be sure to reach out.
Ports are provided with the HardTrack Cloud Sensor, so that the sacrificial temperature sensors can be attached on the outside of the Digi Connect Sensor+.
Yes. Digi Remote Manager offers REST APIs allowing you to ingest data into any platform whether Cloud or Enterprise.
Yes. Digi offers a bundled price for both wireless services and Digi Remote Manager for $2.80 a month. This includes 1 MB of data and Digi Remote Manager Cloud Services.
Wake includes the cost of the Digi Remote Manager subscription in its annual maintenance fees for the HardTrack Cloud Sensor, so that a separate subscription is not necessary.
Digi Remote Manager allows you to set the read and the reporting intervals for Digi Connect Sensor+. The HardTrack Solutions allows you to set the temperature logging interval and the upload or reporting interval to whatever values you prefer.
Yes. The HardTrack Cloud Sensor II (HTC II) is designed to be deployed outside. The HTC II enclosure is waterproof (MIL-STD-810F Immersion – submerged at 1 meter for 30 minutes).
The Digi Connect Sensor’s ASP is $469 which includes batteries. Please contact Wake, Inc. for pricing on the HardTrack Cloud Sensor II. www.wakeinc.com
The sensors are deployed to various locations within the concrete pour, which are typically specified by the project owner’s engineers. For example, at the core/center of the pour, a few inches into the concrete pour at the top, side, or other further distance from the core.
The HardTrack temperature sensors can be used indefinitely. However, it is more typical that they are used until the end of the concrete monitoring period, at which time the concrete is consider cured.
An engineer will specify the temperature parameters for each concrete mix type, and these are entered into the HardTrack application. If concrete maturity is being used, the results of samples are entered into the HardTrack application and standard concrete maturity calculations are used within HardTrack to determine the estimated strength of the concrete at each temperature logging interval.
8 to 30 VDC, so 12 or 24 V are supported.
No. The HardTrack Cloud Sensor II (HTC II) includes rechargeable batteries that last from 60 to 120 days on a single charge, depending upon the number of sensors, the length of the temperature sensor probe cables, the logging interval and the upload or reporting interval. The non-rechargeable backup battery can power the HTC II for several months, should the rechargeable batteries not be sufficient to complete the monitoring of a concrete pour.
We support CAT 1 and plan to support CAT M in the next version of the product.
The Digi Connect Sensor has one DIO port which can support 1 pulse meter.
No, it is a cellular device.
You can communicate to the BLTE radio from a Smart Phone or Tablet using the Digi Connect Wizard Application.
Yes, it is internal.
For most applications, it is usually in close proximity. The limits are the same as any typical cabled sensor in an industrial environment.
Temperature sensor cables can be ordered for the HardTrack Cloud Sensor II, in standard lengths of 1-meter/3.28 feet to 100-meters/328.08 feet.
It is low data rate, so you would want to use an IoT plan from Digi or a mobile operator.
Wake includes the cost of the cellular data plan in its annual maintenance fees for the HardTrack Cloud Sensor, so that a separate cellular data plan is not necessary. The devices arrive preconfigured and ready to use, right out of the box.
Yes, IoT services are widely available and where there is cellular coverage.
It can support any industrial sensor with an analog, 4 to 20 mA, 485 serial or digital output.
No, it just supports 485 Serial Modbus.
No, Band 40 is not supported.
Yes. However, there is a temperature limit of 100°C or 212°F on the temperature sensor cables. Please keep this in mind when deploying the sensors near hot asphalt. Wake can supply the temperature sensor cables within aluminum sheathing, if this is necessary for your application.
Wake also offers wireless sensors that can communicate to either a handheld computer, wireless tablet or a HardTrack Cloud Gateway that is deployed at the construction site to monitor wireless sensors remotely.
Typical users are under 1 MB. It is really application dependent. The Connect Sensor is designed to minimize data traffic over the mobile network to save our customers money.
From any authorized Digi Reseller. You can find these under “How to Buy” on the Digi Connect Sensor product page. Contact Wake, Inc. at www.wakeinc.com, to purchase the HardTrack Cloud Sensor II.
No, using the application interface (API) tools provided by Digi, Wake has fully integrated HardTrack with the Digi Remote Manager, so that all of the functions needed are in HardTrack.
