Product Description

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.

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 includes four solder pads for ground, 3.3V-5.5V power, and 3.3V I2C lines.

This sensor includes a temperature sensor accurate to ±2°C, with data also accessible through I2C. If you need something with more temperature accuracy, please check out the Celsius Temperature Sensor.

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.
