Cracks in buildings, bridges, and other large structures often need to be monitored. This is usually a manual process, which is time consuming and not real-time.

The Telemonitron Crack Sensor is an electronic device that reports the status and progress of a crack over a period of many years. Its battery has an autonomy of at least five years. The sensor is particularly suited to locations that are difficult to access and costly to monitor.

As well as detecting the advance of cracks, the device also monitors vibration.

The device operates on the NB-IoT network.
