How does data offload work on the HOBO MX20 series?

Every HOBO MX20 model has integrated Bluetooth 5 LE. You offload data wirelessly to the free HOBOconnect mobile app on a phone or tablet — no cables, cradles, or proprietary readout devices required. HOBOconnect automatically converts raw pressure into fully compensated water level readings accounting for barometric pressure, temperature, and water density.
