The Speed Measuring Sensor Module (LM393) is a high-precision device designed to measure the rotational speed of motors, wheels, or any rotating object with accuracy. Utilizing the LM393 comparator IC, this module provides reliable speed detection through an optical or reflective sensor mechanism.
Key Features:
- Accurate Speed Measurement: The module uses an optical sensor and LM393 comparator to accurately detect the speed of rotating objects by counting interruptions in a light beam or reflections off a reflective surface.
- Adjustable Sensitivity: The onboard potentiometer allows users to adjust the sensitivity of the sensor, accommodating different types of surfaces and varying light conditions to ensure precise measurements.
- Digital Output: The sensor outputs a digital signal that can be easily interfaced with microcontrollers like Arduino or Raspberry Pi. This digital signal represents the speed of rotation in pulses, making it straightforward to calculate revolutions per minute (RPM).
- Simple Integration: Designed for ease of use, the module comes with a compact form factor and clear pinout labels. It connects effortlessly to your project with standard GPIO pins.
- Wide Application Range: Ideal for robotics, motor control systems, and any project requiring speed measurement. It can be used to monitor the performance of motors in real-time, detect anomalies, or implement feedback systems.
