- The LM393 distance sensor offers stable performance powered by a 3-5V supply. Activate it easily with a simple power switch. - When the sensor detects obstacles within a range of 2-30 cm and at an angle of 35 degrees, green indicators on the circuit board illuminate. The output port provides a continuous signal when an object is detected. - The detection range can be adjusted using a built-in potentiometer. Turn it clockwise to increase the detection distance and counterclockwise to decrease it, ensuring flexibility for various applications. - An adjustable sensitivity knob allows for fine-tuning of the detection distance based on the specific requirements of your environment, making it adaptable for different scenarios. - The sensor actively detects infrared reflections, where the reflective properties and shape of the target are crucial for the detection range. Dark objects yield the shortest detection distance while light-colored objects provide the greatest range. Small objects will be detected at closer distances, while larger surfaces can be detected from farther away. Applications: 1. Use the LM393 sensor in robotics for obstacle avoidance, allowing your robot to navigate its environment smoothly. 2. Implement it in security systems to detect intrusions by monitoring entry points and alerting you when an object is within range. 3. Integrate it with automated systems for smart home projects, enabling lights or alarms to activate when motion is detected nearby.
