Common Questions About SensyRoc II

What is SensyRoc II?+

SensyRoc II is a rugged, reusable wireless concrete sensor by Sensytec with a free iOS and Android mobile app. It provides real-time temperature, maturity, and predicted strength data directly on your phone via Bluetooth.

Does SensyRoc require a subscription?+

No. SensyRoc II comes with a free mobile app for iOS and Android — no subscription or recurring fees required. Data is stored locally on the device and can be exported for reporting.

How is SensyRoc different from SensyCast?+

SensyRoc II connects via Bluetooth to your phone for field use, while SensyCast uses LoRa with a 1-mile range and measures both temperature and electrical resistivity. SensyRoc is ideal for smaller jobs or mobile field monitoring; SensyCast is designed for large-scale, multi-sensor deployments with cloud connectivity.

Is SensyRoc reusable?+

Yes. SensyRoc II features a reusable sensor body with replaceable probes. The rechargeable battery lasts up to 1 year, and the rugged IP67-rated enclosure is built for repeated use on job sites and precast plants.
