Curling iron

HS3144E Application of unipolar Hall element in hair curler

In recent years, with the rapid development of intelligent technology, various intelligent home appliances have become an indispensable part of daily life. Among them, intelligent curling irons, as a new favorite in the field of beauty and hair care, are gradually entering thousands of households.

Hall switches mainly play a temperature control function in curling irons. By sensing the changes in the surface temperature of the curling iron, the Hall switch can adjust the power of the heating element in real time to maintain the set temperature range. Such applications enable curling irons to automatically control temperature, avoid damage caused by overheating, and protect the user's hair quality and scalp health.

Curling irons make hair curly and fluffy through physical heating. It is required that the internal components of the product are not only resistant to high temperatures, but also timely monitor the temperature changes, circuit faults and short circuits inside the curling iron, and protect the health of hair to the greatest extent on the basis of ensuring user safety. In response to this requirement, unipolar Hall switches can meet

These requirements. It is recommended to use HS3144E high-sensitivity unipolar Hall devices.

HS3144E unipolar switch type Hall position sensor is a magnetic sensing circuit composed of an internal voltage regulator, a Hall voltage generator, a differential amplifier, a temperature compensation unit, a Schmitt trigger and an open collector output stage. Its input is magnetic induction intensity and its output is a digital voltage signal. It is a single-pole magnetic sensing circuit suitable for working under rectangular or cylindrical magnets. The operating temperature range is -40 ℃ ~ 150 ℃, the power supply voltage operating range is 3.8V ~ 30V, the load current capacity can reach up to 50mA, and the package form is SIP3L (TO92S).
