Featuring a 5mm slot width and a robust output capability, this module is perfect for integrating with MCU, RPI, and Arduino projects, ensuring clean signal output and reliable performance. ## Description Description: Features: 1, the use of imported groove coupler sensor, slot width 5mm. 2, output status indicator lamp output high, output low lights. 3, block, output high; no shelter, output low. 4, the comparator output signal clean, good waveform, driving ability, than 15mA. 5, the working voltage of 3.3V-5V 6, the output format: digital switching output (0 and 1) 7, a fixed bolt holes for easy installation 8, small PCB board size: 3.2cm x 1.4cm/1.3 x 0.6inch 9, using a wide voltage comparator LM393 Wiring instructions: 1, VCC positive power supply 3.3-5V 2, GND power supply is negative 3, DO TTL switching signal output 4, AO this module does not work Package includes: 5 x Speed Measuring Sensor LM393 5 x Encoders 2 x 10Pin Dupont Cable Female to Male 2 x 10Pin Dupont Cable Female to Female Review: Product performed as expected without the addition of a feedback resistor - I needed a reliable way of determining the velocity and distance driven of my 6WD robot car chassis and this encoder filled the bill. Two of the six wheels on my robot chassis are not motor driven and have a 6 mm shaft available to attach an encoder wheel. I was able to use a precision ream to enlarge the hole in one of the encoder wheels so it was a press fit on the 6 mm shaft. I then centered the encoder board over the encoder wheel and ran a functional test of encoder output which it passed with flying colors.
