The 8 Values Hall Sensor Kit includes a variety of Hall-effect sensors, but they differ in key aspects such as operating principles, sensitivity, and output type. Here’s what sets them apart:

• SS40AF, SS41F, SS49E – These are bipolar Hall sensors, meaning they respond to both north and south magnetic poles. They are commonly used for position sensing.
• A3144E, 3144E – These are unipolar Hall sensors, which means they activate only when exposed to a specific magnetic pole (typically south). They are often used in speed detection and proximity sensing.
• U18, US1881 – These are latching Hall sensors, meaning they remain in their last state until exposed to the opposite magnetic field. They are useful in rotary encoders and brushless motor applications.
• AH3503, OH137 – These are linear Hall sensors, which provide an analogue output proportional to the magnetic field strength. They are ideal for current sensing and precise magnetic field measurements.
• ATS177 – This is a switching Hall sensor, designed for high-speed switching applications.

Each sensor in the kit serves a different purpose, making it versatile for various magnetic sensing applications.
