Bluetooth Range and number of data points

vkadal

I need to collect data from approximately 20000 points. I want to form a BLE mesh network and collect the data. The sensors may be buried below the ground level about 30 to 50 CM deep, and the sensor will be kept in side a concrete / brickwork / rigid PVC / steel chamber. ( The selection of suitable chamber is in our choice) The next data point will be within 5 meters. 

Can your Bluetooth devices work under this condition?

    Thanks for the detailed reply.  As you suggest, I can use a rigid plastic enclosure and avoid moisture. So the range should be as required. The data rate is very slow. May be, one or two data per hour per device. And I can reduce the number of data points to reduce the congestion. That will not be an  issue. 

    Can you suggest me the right part number to do a POC? I have nRF 9160 DK with me

    For Bluetooth Mesh I would recommend the nRF52833 or the nRF52840, depending on your application size. It is easy to port the application between the two, so you should start with either of those DKs. 

    When you have an application that is working, you can port it to the nRF52840 Dongle if you like (less expensive and smaller, which can be used for a larger scale of testing).

    Best regards,
