DFRobot SEN0627 Small-Angle Ultrasonic Ranging Sensor 8m IP67

This compact ultrasonic ranging module is made for accurate long-range distance measurement in outdoor, environmental and industrial monitoring projects. It measures targets from 25 cm to 800 cm, making it useful for water level, liquid level, obstacle and container distance sensing.

A narrow 15° field of view helps focus the acoustic beam and minimise false echoes from nearby walls, pipes or tank structures. The IP67 sealed probe is suited to wet and dusty environments, while onboard temperature compensation helps maintain stable readings across changing conditions.

The sensor uses UART controlled output and is compatible with Arduino development boards. DFRobot provides a product wiki for setup details, and the package includes one Small Angle Ultrasonic Ranging Sensor-8m and one 4Pin sensor cable.
