Hall effect sensors are primarily used for angle detection in Moving Heads (Lights). Moving Heads need to rotate according to preset programs to achieve various lighting effects. Hall effect sensors can sense changes in the magnetic field and convert them into electrical signals. By processing the electrical signals, the current angle of the Moving Head can be accurately calculated. Specifically, the role of Hall effect sensors in Moving Heads can be summarized as follows: Detecting the Moving Heads angle: Hall effect sensors are usually mounted on the rotating shaft of the Moving Heads and form a magnetic circuit together with a magnet. When the Moving Heads rotates, the magnet will move relative to the Hall effect sensor, causing a change in the magnetic field. The Hall effect sensor will sense this change and output a corresponding electrical signal Converting to a digital signal: The output signal of the Hall effect sensor is an analog signal, which needs to be converted into a digital signal through an analog-to-digital converter (ADC) before it can be recognized and processed by the microcontroller. Calculating the Moving Head angle: The microcontroller, based on the digital signal output by the Hall effect sensor and the mechanical parameters of the , can calculate the current angle of the Moving Heads. Controlling the Moving Head movement: The microcontroller controls the driver of the Moving Head according to the preset program and the calculated angle of the Moving Head, so that the flashlight head can shake and rotate along the predetermined trajectory
In summary, Hall effect sensors are essential components in Moving Heads, providing important technical support for the precise positioning and control of the Moving Head.
