BlueRobotics Bar02 High-Resolution Depth/Pressure Sensor Depth measurement range: 10 meters (2-bar absolute pressure) Water depth resolution: 0.16mm / Air pressure resolution: 13cm Compatible with most DroneCode boards including the APM2.6, PixHawk, and others The BlueRobotics Bar02 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 0.16mm! 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). 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 that is compatible with most DroneCode compatible boards including the APM2.6, PixHawk, and others.
