Hi BorisVian, +/-25m is the accuracy of air pressure equivalent to altitude, not the accuracy of water level. After check, to get water level, formula "h=(P-P0)/ρg"—— we're supposed to substitute P as 50pa, ρ as 1000kg/m3, g as 9.8N/kg, and then we can get that h is equal to around 0.005m. To use pressure sensor, the sensor needs to be calibrated first to obtain higher accuracy. ... View more

Hi Digisolve， After you loaded offset & radius and calibration reached to 3. Offset & radius may change because the background calibration algorithm is always running. For your hardware, it is recommended that you generate a SIC matrix and write it to the sensor. ... View more

Hi Digisolve， After the I2C stop signal, the bus will be pulled high. You can try to read one byte at a time, then each byte read will generate a stop signal. By the way, what impact does the current waveform have on your application? ... View more

Hi Digisolve， After you call BNO055_Load_Calibration_Profile(), you need to wait calibration status to reach 3. ... View more
