3. Specifications 

• Model : KE4014

• Sensor type : Optical refraction 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

• Power consumption : Approximately 20mA (when operating at 5V)

4. Working Principle 

This light-dissipating module is based on the principle of light change, 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 of the module.

• Signal control : When light passes through the sensor and is broken, the module outputs a high-level signal; when it is not broken, 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 the light is broken. The sensor outputs a high level when the light is broken and a low level when the light is not broken.

6. Application Scenarios 

Keyes' new 2021 DIY electronic building block light-breaking module is widely used in:

• Education : Used for teaching and experiments in photosensitive sensing to help students understand optical principles and signal control.

• DIY Projects : Suitable for creating photosensitive devices and interactive electronic projects.

• Experiment : Used in experiments to test and demonstrate the response to light-breaking signals.
