Gravity: 360 Degree Hall Angle Sensor

SKU: SEN0221

The Hall Angle Sensor is a miniature 360° sensor using the Hall effect. Compatible with DFRobot Gravity interface, it runs on 5V DC and has 0~5V analog output for direct Arduino use. It converts rotational angle to a proportional electrical signal. With a robust aluminum shell, Hall non-contact tech, and high-speed stainless steel bearings (reducing friction), it offers long life, compact size, high resolution, and smooth rotation. It performs in harsh industrial environments, resisting electromagnetic interference, water, oil, vibration, and shock.
