Hall Element Application on Bluetooth Headset
Bluetooth headset is the application of Bluetooth technology in hands-free headset, so users can get rid of the original headphones troubled, more convenient to a variety of ways to easily call or entertainment.
Due to the unique properties of Hall devices (solid structure, small size, light weight, long life, easy installation, low power consumption) is far superior to the reed pipe, is also widely used in the Bluetooth headset industry. Because Bluetooth headset power saving, support for long time calls, low-cost features, which determines the choice of the Hall element requires energy saving, low cost, small size.
Hall components are mainly divided into unipolar Hall element, bipolar (latch) Hall element, linear Hall element, all-pole Hall element on the market.The one widely used in Bluetooth headset is unipolar low-power Hall switch consumption.
The main features are:
Noise protection, chopper stabilization technology, ultra-low voltage can reach as low as 1.65V，
High sensitivity, consistency and stability.

What is the Method to Detect the Switching Hall IC?
When we use the Hall element to repair the machine, we will encounter the situation that the Hall does not work, and it is impossible to distinguish whether the Hall element is damaged from the shape of the Hall. The following teaches you how to detect whether the switch type Hall element is damaged.
What Is The Difference Between The PNP And NPN Outputs Of The Hall Switch?
Hall switches often have NPN and PNP outputs, and many people confuse the two output concepts. Now let‘s explain the two differences in detail.
Let’s Know about The Hall Effect Magnetic Sensor
The output voltage, also known as the Hall voltage, (VH) of this fundamental Hall Element is directly proportional to the strength of the magnetic field passing through the semiconductor material (output ∝ H). This output signal voltage can be very small, just a few microvolts even if exposed to strong magnetic fields so many commercially accessible Hall effect devices are produced with built in DC amplifiers, logic switching circuits and voltage regulators to enhance the detectors sensitivity, hysteresis and output voltage.
The Working Principle Of Linear Hall Sensor
A Linear Hall Sensor converts a mechanical displacement through a potentiometer element into a resistive or voltage output that is linear or arbitrary as a function of it. Both ordinary linear potentiometers and circular potentiometers can be used as linear displacement and angular displacement sensors, respectively. However, a potentiometer designed to achieve the purpose of measuring displacement requires a certain relationship between the change in displacement and the change in resistance. The movable brush of the Linear Sensor is connected to the object to be measured.
Odometer Sensor Detection Method
The odometer sensor is generally Hall Effect Sensor. You can use a multimeter to test resistance, or test continuity.
Do you know the Precautions when using Hall IC?
Do you know the Precautions when using Hall IC? As a Hall Sensor Suppliers, share with you.
Linear Sensors for Medical System
Linear Hall IC is widely used in different fields. Many programs need linear motion to be tracked for system management or to guarantee security. Modern devices utilized in the health care industry need complex. Linear sensors offer you a solution for monitoring the position of tables. For more complex programs, such as fluoroscopy or radiography surgical or tables C-arms, that need coordinated placement of many components,complete rotary encoders are a superb alternative.
Do You Know the Application of Hall Sensor Technology in the Automotive Industry?
Hall sensor technology has a wide range of applications in the automotive industry, including power, body control, traction control, and anti-lock braking systems.
Hall Application in Electric Car Brake
Hall effect technology can be widely used in many applications. The principle of electric car brake is to make a braking action, the brake signal is passed to the controller, the controller receives the brake signal, immediately stop the power supply to the motor, thus protecting the driver‘s safety, when the electric car brakes must be immediately Feedback to the brushless motor to stop turning, so the electric car brake on the general use of the faster response to the unipolar Hall and all-pole Hall.
