We have used the Bar30 Pressure sensor in a under water camera to measure both temperature and pressure, the depth is between 1-15 m. We have also some other cameras which have a temperature sensor which are more accurate. The Bar30 Pressure sensor shows a difference around 6 degrees from this more accurate temp sensor.
We tested the Bar30 sensor in air before we put it in the water, and then it was showing the right temp. Do you have any idea what is wrong?
We are using a raspberry pi with python.
Are there any way to calibrate the sensor?
Thank you in advance
