LM393 Motor Speed Sensor Module
RWF 3,900
RWF 3,500
The LM393 Motor Speed Sensor Module is a sensor designed to measure the rotational speed of motors. It uses an LM393 comparator chip to process the signals generated by a rotating motor, providing accurate speed readings. The module works by detecting changes in the magnetic field produced by the motor's rotor or other moving components, converting these variations into digital pulses. These pulses are then counted and processed to calculate the motor's speed in revolutions per minute (RPM). It is commonly used in motor control systems, robotics, and automation projects to monitor motor performance and adjust settings for optimal efficiency. The module operates with a wide voltage range, making it versatile for various applications.
