The LM393 Test Motor Speed Counter Sensor is an essential component for measuring the speed of motors in various projects, particularly those involving DC motors or stepper motors. It uses the LM393 comparator IC to process and measure the speed of rotation by counting the number of rotations or pulses over time. This sensor is perfect for applications in robotics, motor control systems, and speed monitoring systems where accurate measurement of motor speed is needed.
Key Features:
-
LM393 Comparator IC: Utilizes the LM393 comparator IC to detect changes in the signal from a rotating object (e.g., motor shaft), providing a reliable digital output.
-
Speed Measurement: This sensor counts the number of pulses per unit of time to calculate the RPM (Revolutions Per Minute) of the motor, allowing you to monitor motor performance or control speed in real-time.
-
Pulse Output: Provides a digital output that sends pulses corresponding to each revolution or increment in the motor’s rotation, which can be easily interpreted by a microcontroller.
-
