## Overview

The RIDEN 5Pcs Speed Measuring Sensor LM393 is a high-performance tacho sensor designed for DIY enthusiasts and professionals alike. Featuring a 5mm slot width and LM393 wide voltage comparator, this module provides reliable speed detection for motors and encoders, making it an essential tool for any tech-savvy project.

## Description

Features: 1. Use a slot-type optocoupler sensor with a slot width of 5mm 2. There is an output status indicator light, the output high level light is off, and the output low level light is on. 3. With shielding, the output is high level; without speed gear, the output is low level. 4. Comparator output, clean signal, good waveform, strong driving ability, more than 15mA 5. Working voltage:3.3V-5V 6. Output form: digital switch output (0 and 1) 7. There are fixed bolt holes for easy installation 8. Small board PCB size:3.2cmx1.4cm9. Use wide voltage LM393 comparator  Applications: 1. When there is no block in the module slot, the receiving tube isturned on, and the module DO outputs a low level; when blocked, D0 outputs a high level; 2. The DO output interface can be directly connected to the IO port of the single-chip microcomputer to detect whether the sensor is blocked. If the motor code disc is used,the motor speed can be detected 3. The module DO can be connected with a relay to form a limit switch and other functions, and can also be connected with an active buzzer module to form an alarm. 4. Widely used in motor speed detection, pulse counting, position limit, etc.  Wiring instructions: 1. VCC is connected to the positive pole of the power supply 3.3-5V 2. GND is connected to thenegative pole of the power supply 3. DO TTL switch signal output 4. AO 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

## Features

- the use of imported groove coupler sensor, slot width 5mm.
- It has the output state light, if output high level, the lights are off. if output low level, it on.
- If it covered, it will output high level; otherwise, its output low level.
- Use the LM393 wide voltage comparer.
- The DO output interface can be directly connected to a micro-controller IO port if there is a block detection sensor, such as the speed of the motor encoder can detect.
