Hello Robin, thanks for replying. I haven't tried putting it on water yet. I'm still in design & planning stage. So far, i only tested the sensor on my home putting the sensor static in a table for 3 days and the altitude change drastically (40m - 80m). As for the water, the Dam has pretty calm water condition. Also, i dont mind a little inaccuracy as long the objective is carry out. Anyway, i read about the solution on internet that i can put 2 BMP sensor on same level (1 on water and 1 on land), then calculate the altitude difference between 2 BMP. Will that work ?
