About this product
The LM393 RPM measurement sensor is a simple and inexpensive way to measure the rotational speed of a motor or other rotating device. RPM measurement sensor consists of an infrared LED and a phototransistor, which are mounted on a small PCB. When the LED is turned on, it emits a beam of infrared light. If the beam is interrupted by the rotating shaft, the phototransistor will detect the interruption and generate an electrical pulse. The number of pulses per second is proportional to the rotational speed of the shaft.
The LM393 RPM measurement sensor can be used with a microcontroller to measure the rotational speed of a motor or other rotating device. The microcontroller can count the number of pulses per second and then convert the count to RPM
The LM393 RPM measurement sensor can operate on a voltage range of 3.3V to 5V. The input voltage is applied to the VCC pin of the sensor. The sensor will output a TTL signal on the DO pin, which is active low. The output signal will be high when the sensor is not detecting any pulses, and it will be low when the sensor is detecting pulses.
The LM393 RPM measurement sensor works on the principle of optical coupling. The sensor consists of an infrared LED and a phototransistor, which are mounted on a small PCB. When the LED turned on, it emits a beam of infrared light. If the beam interrupted by the rotating shaft, the phototransistor will detect the interruption and generate an electrical pulse. The number of pulses per second is proportional to the rotational speed of the shaft.
The LM393 Rotational Speed Measuring Module is a versatile and easy-to-use tool for measuring rotational speed. It is relatively inexpensive and can use with a variety of microcontrollers. Here…
