KY-003 Hall Effect Magnetic Sensor Module | Robochacha Pakistan

Makers choose the KY-003 Hall Effect Sensor Module when they need to detect magnets without any physical contact. Specifically, the module uses a 3144 Hall Effect IC to sense the proximity of a magnetic pole. Therefore, when you bring a magnet close to the sensor, the module sends a digital signal to your Arduino. Furthermore, the board includes a built-in LED and a pull-up resistor. As a result, you can view the sensor status visually and connect it directly to your microcontroller with zero extra parts.

Additionally, this sensor excels in high-speed applications. Consequently, engineers use it frequently for measuring motor RPM by counting how many times a magnet passes the sensor. Because of this, the KY-003 Hall Effect Sensor Module is a critical component for speedometers, tachometers, and non-contact limit switches.

Key Features

• Non-Contact Sensing: The module detects magnetic fields through plastic, wood, and glass. Specifically, this makes it ideal for sealed or waterproof enclosures.

• Fast Response Time: It switches states in microseconds. Therefore, it accurately tracks high-speed rotating parts in motors and fans.

• Dual Output Indicators: You get a digital signal for your code and a built-in LED for visual debugging. As a result, troubleshooting your circuit becomes much easier.

• Standard 3-Pin Interface: The KY-003 Hall Effect Sensor Module uses a standard G-V-S layout. Consequently, it plugs directly into Arduino sensor shields.

• Compact Design: In addition, its tiny footprint allows you to mount it in tight spaces, such as inside a 3D printer frame or a robot arm.
