The Bar02 Ultra-High Resolution 10m Depth/Pressure Sensor is a low-pressure, high resolution, high accuracy version of our 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 0.16mm! It can also measure altitude in air using air pressure with a resolution of 13cm. 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 4-pin DF13 connector, however it is not compatible with ArduSub or the BlueROV2.

This sensor includes a temperature sensor accurate to ±2°C, with data also accessible through I2C.

The electrical schematic and board layout are open-source and the design files are available in the Technical Details tab. Feel free to adapt for your own needs.

The gel-filled sensor must be completely dried once per day or the pressure and temperature readings will drift.
