hall sensor what is it?

Answer 1

The Hall Sensor measures the hall effect, the instantaneous point where the flywheel's magnet changes from a north to a south pole. When the pole change occurs, the device sends a single, tiny pulse to the CDI box which triggers it to dump the energy from the charging capacitor into the high voltage transformer.

Thus, Hall effect sensor is a transducer that varies its output voltage in response to changes in magnetic field density. Hall sensors are used for proximity switching, positioning, speed detection, and current sensing applications.

In its simplest form, the sensor operates as an analog transducer, directly returning a voltage. With a known magnetic field, its distance from the Hall plate can be determined. Using groups of sensors, the relative position of the magnet can be deduced.



CDI box (def) : Capacitor discharge ignition (CDI) is a automotive electronic ignition system which is widely used in motorcycles, lawn mowers, chain saws, small engines and recently in some cars. Capacitor discharge ignition uses capacitor discharge current output to fire the spark plugs.

Answer 2

A Hall sencer is nothing but a position sencer in a mechanical system[to find out the position of a particular arm, wheel or any moving part for that matter at given time] which is working on the electromagnetic principle. Well that is the simplest explanation.

Answer 3

That's used by Ford in their distributor systems. It works on the principle of inductive pickup. It works, but Ford will probably be bankrupt soon. It's just another method of distributing the spark to the proper spark plug wires, that's all.

Answer 4

It's a transistor type device that senses the presence of a magnetic field.
