IP68 Underwater Ultrasonic Sensor 6m with UART

This ultrasonic sensor from DFRobot is built for underwater use and measures distances of 5 to 600 cm there. It is sealed to IP68, is supplied with 5 to 24 V and outputs the distance on request via UART, according to DFRobot even at a water depth of 10 m. This allows obstacles in front of underwater vehicles to be detected or the water depth to be measured.

For shorter distances from 2 cm there is the IP68 Underwater Ultrasonic Sensor 3m with UART.

Important: The sensor only measures under water. In air it does not provide usable values because it needs water as the transmission medium (DFRobot).

Features:

• Underwater distance measurement 5 to 600 cm
• Small design and small blind zone
• Response time 14 ms
• Waterproof to IP68
• Wide voltage range 5 to 24 V, current consumption max. 10 mA
• UART, measurement on request

Application Examples:

• Obstacle detection on underwater robots and underwater drones
• Measuring water depth below a boat or robot
• Distance to pool and tank walls under water
