Gravity: 360 Degree Hall Angle Sensor is a compact magnetic rotation measurement module built on the principle of the Hall effect. Designed for seamless integration with the DFRobot Gravity interface, this angular sensing unit operates from a 5V DC supply and produces a proportional 0–5V analog signal compatible with Arduino and other microcontroller platforms. The precision rotation sensor converts shaft movement directly into electrical output, enabling accurate measurement of continuous 360° motion in robotics systems, mechanical control assemblies, and embedded automation projects.
High‑Resolution 360° Non‑Contact Angle Detection
This magnetic rotation detection module converts shaft angle into a proportional analog voltage, allowing precise monitoring of rotational position across a full 0–360° range without mechanical stops. Hall‑based sensing eliminates physical contact between internal components, reducing wear while maintaining stable signal output. The integrated design provides smooth rotation, low dynamic noise, and high measurement consistency, making the angular measurement board suitable for applications such as steering feedback systems, crank angle detection, and automated motion monitoring.
Industrial‑Grade Mechanical Construction
The angular sensing unit features a durable aluminum alloy housing designed to withstand demanding environments. High‑quality imported stainless steel bearings minimize friction during rotation, improving responsiveness and longevity. This robust construction enhances resistance to vibration, shock, oil, and electromagnetic interference commonly encountered in industrial installations. The combination of mechanical durability and contactless sensing technology supports reliable long‑term operation in motion control systems, robotics platforms, and equipment monitoring solutions.
High Precision with Fast Signal Response
The compact rotation measurement board delivers fine angular resolution of 0.088° when paired with a 12‑bit ADC. Rapid refresh performance down to 0.2 ms allows responsive tracking of dynamic motion, enabling real‑time control feedback in embedded systems. Stable analog output ensures accurate interpretation by microcontroller analog inputs, while the low operating current maintains efficient system power consumption for robotics mechanisms and automation hardware.
