Signal Sensor™
How deep should the sensor be installed?
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.
What range of wireless connection should I expect from the sensor?
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.
Can I collect measurements when my phone is not connected to WiFi or data?
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
How long do I need to wait to collect all the data from a Signal sensor?
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.
