Gravity: Linear/Analog Hall Sensor is a high-precision device designed for measuring and monitoring magnetic field strength. Advanced Hall effect circuitry at the core converts magnetic induction strength directly into a voltage output. The sensor responds uniquely to magnetic fields: when the south pole of a magnet faces the sensing surface, the magnetic field strengthens, and the output voltage rises above the midpoint, gradually increasing. When the north pole faces the sensing surface, the output voltage falls below the midpoint, gradually decreasing. High sensitivity makes this sensor ideal for applications that need precise magnetic field detection, such as industrial control, scientific research, security systems, and various electronic devices.

Magnetic Field Sensor Output Voltage Graph

In summary, Gravity: Linear/Analog Hall Sensor is an efficient and accurate tool for detecting magnetic fields. It offers reliable performance and precise measurements, making it an invaluable addition to projects.
