Bar02 Ultra High Resolution 10m Depth/Pressure Sensor
This pressure sensor can measure up to 2 bar absolute pressure (10m depth) with a depth resolution of 0.16mm and an in-air altitude resolution of 13cm. It is waterproof and ready to install.
It’s housed in the same penetrator form factor as the Bar30 and can handle up to 10 bar absolute pressure (90 meter water depth). One of the key features of this version of the sensor compared to the Bar30 sensor is the very high accuracy. According to the datasheet, the worst case accuracy is about +/- 4 mbar (4 cm water depth).
The sensor communicates over I2C. It operates on 3.3V I2C voltage but can accept power input up to 5.5V. It comes standard with a JST GH connector, however it is not compatible with ArduSub or the BlueROV2.
