Exploring optical and magnetic sensors

+

17/6/2003· Magnetic sensors Probably the simplest magnetic sensor to use in an embedded application is a Hall effect sensor. The Hall effect, discovered by Dr. Edwin Hall in 1879, is the production of a voltage in a currentcarrying semiconductor in the presence of a magnetic field.

+

A door and window contact sensor consists of two parts. These parts are a sensor and a magnet. The sensor goes on the door or window frame. The magnet goes on the moving portion of the door or window. For proper operation, the magnet will usually need to be within inches of the sensor when the door or window is closed.
