Description
The WPSE347 is a LM393 speed sensor module, widely used in motor speed detection, pulse count, position control, etc.
The sensor is very easy to operate: To measure the speed of a motor, make sure the motor has a disk with holes. Each hole should be equally spaced on the disk. Every time the sensor sees a hole, it creates a digital pulse on the D0 pin. This pulse goes from 0V to 5V and is a digital TTL signal. If you capture this pulse on a development board and calculate the time between the two pulses, you can determine the revolutions speed: (time between pulses X 60)/number of holes.
For example, if you have one hole in the disk and the time between two pulses is 3 seconds, you have a revolutions speed of 3*60 = 180 rpm. If you have 2 holes in the disk, you have a revolutions speed of (3*60/2) = 90 rpm.
This product is a replacement of: VMA347
Features
- Broad voltage compatibility: This module operates reliably within a voltage range of 3 to 5 VDC, making it suitable for various electronic applications.
- Digital pulse output: The sensor generates digital pulses on the D0 pin with each detection of a hole in the disc, allowing you to quickly and accurately calculate the motor’s speed.
- Versatile applications: This module is versatile and suitable for various applications, from automation, home automation and robotics to environmental and industrial monitoring.
- STEM project: Develop and improve your STEM skills and acquire the knowledge, skills and experience needed to face the technological challenges of the future with this educational kit. This educational kit will trigger a number of processes such as problem-solving, investigative and creative thinking.
- Made in Belgium: Whadda is a unique brand from Belgium’s Velleman Group that offers DIY projects for hobbyists or makers who want to immerse themselves in electronics, programming and mechanics.
