Bar02 – 0-2 bar (10 m)

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.
