Editorial interest 82/100 Selection signal · not a rating of the site

A Bluetooth sensor system that tracks concrete temperature and presents estimated strength readings for construction decisions.

Landing page captured for the 2026-09-13 issue.

Field notes

The system separates the reusable Bluetooth hardware from an approximately €1 disposable temperature probe, allowing the electronics to return to service after each pour. The page says readings are logged every 15 minutes and converted into MPa estimates through the Sadgrove maturity method. Its displayed validation table compares four curing points with crush-test results, while the app is described as adding forecasts, project records, and PDF reports.
