Before you start

Before you start using Maturix there are a few important things you need to know to ensure correct operation.

Good Sigfox coverage on-site is required

The Maturix transmitters send temperature data to the cloud using the wireless IoT network, Sigfox. It is important that there is Sigfox coverage at the construction site where you will be monitoring, otherwise, the data will not be received and stored in the cloud.

You can check the estimated Sigfox coverage using these tools: coverage.sigfox.cz or coverage.iotdk.dk/en

When you are creating a new project in Maturix In-situ, you will see a coverage estimation below the project location/map.

We recommend installing a gateway on-site to ensure great connectivity without loss of data.

Contact your reseller if you would like to purchase a Sigfox gateway.

The transmitters do not store any data. After the temperature has been measured, the reading is immediately transmitted using Sigfox. Therefore, if you are in an area with limited Sigfox coverage, the reading might not be received. However, installing the Sigfox gateway close to the site will provide good coverage – and all the readings will be received and stored in the cloud.

Occasional battery service of the transmitters is required

The current version of Maturix transmitters have integrated lithium batteries that must be replaced by the reseller when the batteries have reached their end of life. You must ship the transmitters to your reseller, who will refurbish or swap the devices, and return them with new and fresh batteries ready for use.

If a device has been sending more than 20.000 transmissions, a “consider battery service” icon will be shown under Devices.

→ We recommend that you perform a system test every time before installation.

The battery life of a Maturix transmitter is around 15 months when used 50% of the time and 8 months when used 24/7 (under normal conditions).

Test the system before use

Each time, before you use Maturix for concrete monitoring, you should perform a system test on-site to ensure that everything is working as intended and that there is connectivity at the place where the Maturix Transmitters will be installed and will send data from.

We recommend performing the test on-site, at the exact location where the monitoring will take place, at least five days in advance, so potential connectivity issues or errors can be resolved before casting.

How to perform a system test

  1. Prior to the test: Ensure that there are no visible damages, loose parts, water inside the transmitter, or other errors that could affect the operation
  2. At the location of installation: Connect a type K thermocouple to each transmitter to start temperature measurement and data transmission (the LED on the transmitter will light up and start blinking)
  3. Log in to the Maturix™ Web Portal and click on Devices under the project they are added to. When a thermocouple is connected, and there is connectivity on-site, a temperature reading will be displayed under the “Status”-column within a few minutes.
  4. If all the transmitters have sent data, everything should be working as intended. After the system test, disconnect the thermocouples from the transmitters to preserve battery life.

If no data is received it can be due to:

  • Data not yet received → Update the webpage
  • No cable registered as connected → Make sure the cable is connected
  • No coverage at the location of the transmitter → Reposition the transmitter or install a Sigfox gateway
  • Gateway not installed correctly → Follow the installation guide

If you still experience problems, immediately contact your reseller.

Maturity calibrations are required for strength prediction

Maturix estimates the concrete strength using the Maturity Method. The strength-maturity relationship for each concrete mixture must be determined and entered into the Maturix Web Portal.

→ We recommend obtaining the strength-maturity relationship from the concrete supplier in good time, as the calibration procedure for each concrete mix normally can take up to 28 days.
