KY-024 4pin KEYES Linear Magnetic Hall Switches Speed Counting Sensor Module for Arduino

1 x Linear Magnetic Hall Sensor Module For Starters Compatible KY-024

Package included:

Hall switch integrated circuit using hall effect principle, USES the semiconductor integrated technology manufacturing magnetic

susceptibility of the circuit, it is by the voltage regulator, hall voltage generator, differential amplifier, schmidt triggers,

temperature compensation and the open collector output stage circuit composed of magnetic sensitive sensor circuit,

its input for the magnetic induction intensity, the output is a digital voltage signal.

• Can detect the intensity of the sound environment

• Sensitivity adjustable (shown in blue digital potentiometer control)

• With the retaining bolt hole, convenient installation

• Output form digital switch output (0 and 1 high and low level)

• Signal output indication

• Single channel signal output

• The output effective signal is low level

• When there is sound,outputs low level and the signal light

• Can be used for Acoustic control light , give sound and light alarm working with Photosensitive sensor ,and sound control,sound detect

• Circuit board output switch quantity

• Working voltage:DC 3.3-5V

• Small board PCB size: 3.4 x 1.6 cm
