Hi there. I’ve been trying to use a series of bar30 depth sensors to continuously monitor the depth of water in a bucket with an arduino. Each time I turn on the arduino the sensor gives a different depth, usually +/- 10 cm off. I haven’t found a way to calibrate or equilibrate the sensor with air pressure. The depths I seek to measure are pretty small, and 10cm is way off compared to the accuracy the sensor is rated to. How do I get calibrated or more accurate readings?
Thanks,
Karly
