The Bar02 Ultra High Resolution 10m Depth/Pressure Sensor is a low-pressure, high resolution, high accuracy version of the Bar30 sensor. Using the MS5837-02BA sensor from Measurement Specialties, this device can measure up to 10-meter depth (2 bar absolute pressure) with a water depth resolution of just 0.16 mm.

It can also measure altitude in the air using air pressure with a resolution of 13cm. It is 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 3.3 V I2C voltage but can accept power input up to 5.5 V. It comes standard with a JST GH connector.

Note: This sensor is NOT compatible with ArduSub or the BlueROV2.
