We recommend installing the Converge Signal sensor up to 100mm below the concrete surface, and making sure the face with the QR code is facing up.
Once in concrete, the sensor range could be up to 8m, depending on the rebar configuration around the sensor and the sensor installation depth. Please ensure that you are closer than 8m and the Converge app is on your phone screen (not background) when communicating with the device.
If you can't access the internet where the sensors are placed, the mobile app will download the measurements over Bluetooth and store them locally on the phone. But make sure to connect your phone to WiFi or mobile data, as soon as you can. Then, open the Converge app to upload the stored measurements
The app takes about a minute per day of sensor readings/data. For example, if the last collection was done on Monday, and then you go to collect data again on Thursday, there will be three days of data to be collected on the device. This data collection will take around 2 minutes or less.

The Signal sensor system is a fully embedded concrete monitoring solution with a wireless communication range of up to 15m or 50ft. The Helix sensor system is a non-embedded and reusable system with a longer range of up to 1.3km or 0.8miles.
If the Signal Live Hub loses connection with the Signal devices or if the hub goes offline, it will collect historic data and transmit it when it regains connection, ensuring that no data is lost. Users can also manually collect data with the ConcreteDNA App on their smartphone at any time.
The Signal Live hub is currently available in UK, EU, US, Canada, Australia and NZ, Singapore, Hong Kong and India.
When in concrete, the Signal Live Hub will be able to detect Signal devices up to 15m or 50ft away, depending on the rebar configuration around the device and the site environment in which it is in, e.g. number of obstructions between the hub and the Signal devices.
“With Converge Signal we get real-time data to our mobile phones and to the dashboard, giving us a realistic understanding of how the slab is behaving, allowing us to strike as soon as possible and saving us huge amounts of time and money.”
