Subsea Sensors

Blu-Sub subsea sensors provide precise depth and temperature measurements for underwater systems ranging from compact ROVs to long-term ocean deployments. Our lineup includes compact M8 and M10 depth sensors using the MS5837 chip for lightweight, low-power builds, a rugged stainless steel M14 depth sensor with a metal diaphragm for maintenance-free, continuous submersion, and a high-accuracy M10 water temperature sensor rated to 1,000 m. Each sensor is pressure-tested, easy to integrate with common platforms like ArduSub and Pixhawk, and engineered for reliable operation in demanding marine environments.
