49E hall magnetic sensor Arduino Tutorial | tecno4 | Scoop.it
A Hall sensor is a device that allows us to perform magnetic field measurements. Hall sensors are widely used. For example, in the automotive industry, they are used for the functions of the safety vehicle, or the measurement of the position of the camshaft. They are also used to measure fluid velocities, metal detection, induction factors, among many other applications. An important advantage of Hall sensors is that they perform the measurement remotely, without the need for physical contact. Although its scope is limited. They are also immune to noise and dust. This translates into reliable and durable sensors.
