Hall Sensor Applications
Usually, the Hall effect sensor is connected to the circuit, allowing the device to operate in digital (on / off) mode, in which case it can be called a switch. Common equipment in the industry, such as cylinders, are also used in everyday equipment, such as some printers use them to monitor the lack of paper and open covers. When the keyboard is required to have high reliability, the Hall sensor is also designed in its keys.
Hall effect sensors are commonly used to measure the speed of wheels and axles, for example, on the ignition timing (timing) of an internal combustion engine or a tachometer. It is used in brushless DC motors to detect the position of permanent magnets.
