- The LM393 comparator operates reliably with a power supply of 3-5V, ensuring stable performance for your applications. - Equipped with advanced sensors, this module actively detects IR reflections. The detection distance varies based on the object's color: black objects reflect less, resulting in shorter distances, while white objects provide maximum detection range. Smaller items are detectable at shorter distances, while larger surfaces can be detected from further away. - The output connection is designed for easy integration, allowing you to directly connect it to a single-chip microcontroller or control a 5V relay. The connection setup is straightforward: GND connects to GND. - A sensitivity adjustment knob enables you to fine-tune the detection distance based on your specific environmental needs, making it versatile for various applications. Applications: - Ideal for robotics projects where object detection is crucial for navigation and obstacle avoidance. - Perfect for automation systems that require precise sensing for triggering actions based on object presence. - Useful in security systems for detecting intrusions or monitoring areas by recognizing the presence of individuals or objects. This product combines functionality, ease of use, and adaptability, making it a valuable addition to any electronic project or system requiring reliable IR detection.
