Product Description

These are the board-level versions of our Bar Depth and Pressure Sensors for tight integration into projects.

There are two models:

The Bar02 is a low-pressure, ultra-high resolution sensor using the Measurement Specialties MS5837-02BA. It measures up to 2 bar (about 10 meters water depth) with a depth resolution of just 0.16 mm and can also measure in-air altitude with 13 cm resolution. This makes it ideal for shallow-water devices where a high level of resolution is required. It includes a temperature sensor accurate to ±2 °C and is supported in ArduSub 4.7 and later.

The Bar30 is a high-pressure sensor using the Measurement Specialties MS5837-30BA. It measures up to 30 bar (about 300 meters water depth) with a depth resolution of 2 mm, making it a great choice for deep-water ROVs and general underwater instrumentation. The built-in temperature sensor has ±4 °C accuracy, and is supported by ArduSub and other ArduPilot firmware.

Both communicate via I²C and operate on 3.3 V logic (with 5.5 V max power input). The PCB includes four solder pads for ground, 2.5–5.5 V power, and 3.3 V I2C connections.

1 Maximum mechanical pressure is the highest pressure the sensor can withstand before sustaining permanent damage.
2 Depth values assume 1 bar atmospheric pressure and freshwater density (1000 kg/m³); actual values may vary.
3 Applies only to standard pressure range; see MS5837-02BA datasheet for extended.
4 Dry the sensor daily for 2 hours to maintain accuracy; long-term submersion may cause damage.
