The Hall element mainly plays the role of electricity measurement in the electric meter. When the electric meter is powered on, the current coil and the voltage coil Hall generate a magnetic field, forming a torque on the aluminum disk, and driving the timer to count through the transmission gear. The larger the current and voltage, the larger the torque, the faster the counting, and the more electricity is used, so as to measure the amount of electricity used. After the electric meter is powered on, the aluminum disk rotates, and the current coil and the voltage coil in the meter generate a magnetic field, and then the gear rotates and generates induction with the Hall element to measure the amount of electricity used.

HS138S is a highly integrated omnipolar magnetic switch sensor that integrates AMR magnetic sensor and high-precision CMOS processing circuit in an ultra-small package.
The CMOS processing circuit provides a precisely controlled BOP/BRP offset voltage compensation circuit and push-pull output, achieving an industrial-grade operating temperature range (operating temperature: -40～125℃), while providing a wide voltage operating range (2.0V～5.5V) and microampere-level current consumption, suitable for battery-powered applications such as various handheld devices. Omnipolar magnetic switches can greatly simplify installation and use requirements because they do not need to identify the north and south poles of the magnet.
Utilizing the high-speed response characteristics of AMR, this switch combines high response frequency, low power consumption, small size and excellent temperature characteristics, making it the first choice for many low-power, high-performance applications.
HS138S uses two package forms: SOT23-3 and TO-92S.
