The Bar100 pressure sensor is a high-pressure underwater pressure sensor that is sealed from the water and ready to install in a watertight enclosure on your ROV, AUV, or other project. This sensor can measure depths down to 1000 meters, so you can go deeper than ever before!
The sensor is the Keller LD Series pressure/temperature sensor with I2C communication. It has a pressure resolution of 3 mbar, providing a depth measurement resolution of 3 cm in the water column! It operates on 3.3V I2C voltage but can accept power input up to 5.5V, just like the Bar30. It comes standard with a 4-pin DF13 connector that is compatible with most autopilots including the PixHawk and others.
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 anodized aluminum body was designed around the cable penetrator design and is compatible with all of the watertight enclosures.
This sensor is fully supported in ArduSub and works on the BlueROV2. We also have Arduino and Python libraries available below to make this sensor as easy to use as possible! Please make sure that if you use it with a 5v board, such as the Arduino, that you use a Level Converter.
