3. Specifications 

• Model : KE4016

• Sensor type : Hall sensor

• Wire length : 200mm

• Operating voltage : DC 3.3V - 5V

• Interface type : 3-pin anti-reverse connector with a 2.54mm pitch

• Positioning hole size : 3mm in diameter

• Dimensions : 32mm x 23.5mm x 12mm

4. Working Principle 

This Hall sensor module is based on the Hall effect principle, and its working principle is as follows:

• Power connection : The module is connected to the power supply through the GND and VCC ports, and supports an operating voltage range of 3.3V to 5V to ensure normal operation.

• Signal control : When the Hall sensor detects a magnetic field, the module outputs a high-level signal; when no magnetic field is detected, it outputs a low-level signal.

• Connection configuration : The modular design facilitates quick assembly and disassembly, while the red anti-reverse insertion terminals and wires ensure safe connection and reduce the risk of incorrect connection.

5. Foot position description 

The module's pin definitions are as follows:

• VCC : Connect to the positive terminal of the power supply to provide the required voltage to the module. Ensure it is between 3.3V and 5V to avoid damage.

• GND : Connects to the negative terminal of the power supply to ensure the module works properly and provides a stable reference power.

• S (Signal Terminal) : Outputs a signal when a magnetic field is detected. The Hall element outputs a high level when it senses a magnetic field and a low level when it does not detect one.

6. Application Scenarios 

Keyes' new 2021 DIY electronic building block Hall sensor is widely used in:

• Education : Used for teaching and experiments on the Hall effect, helping students understand the principles and applications of magnetic field sensing.

• DIY projects : Suitable for developing electronic devices related to magnetic fields, such as switches and sensors.

• Experiments : Used in various experiments to test and demonstrate the response and control of Hall sensors.
