LV101 : Proximity sensor
LV107110 : Hall effect sensor
Anemometer : Hall effect sensor (LV 107, LV 110) Rotation of the shaft of the vane powers a circular magnet of 8 poles. A dual Hall effect sensor, placed next to the magnet senses the signals of magnetic field polarity transition. The sensor signal is converted to electrical frequency and is proportional to the air velocity. Signal chronology allows the detection of rotation direction.
