Speed Measuring Sensor

Description

Speed Measuring Sensor

Features

• using imported trough type optical coupling sensor, groove width 5 mm.
• the output state light, lamp output level, the output low level light.
• covered, output high level;Without sunscreen, the output low level.
• the comparator output, signal clean, good waveform, driving ability is strong, for more than 15 ma.
• the working voltage of 3.3 V to 5 V
• output form: digital switch output (0 and 1)
• a fixed bolt hole, convenient installation
• small board PCB size: 3.2 cm x 1.4 cm
• use the LM393 wide voltage comparator Module

USES:

• The module without slot, the receiving tube conduction, module DO output low level, shade, the DO output high level;
• the DO output interface can be directly connected to a microcontroller IO port, if there is a block detection sensor, such as the speed of the motor encoder can detect.
• DO modules can be connected to the relay, limit switch, and other functions, can also with the active buzzer module, alarm.Product connection details:The positive 3.3-1, VCC power supply 5 v2, GND connect power cathode
• DO TTL switch signal output4, AO the module does not workShipping list:A speed measuring sensor module

Wiring specification:

VCC Connect the positive 3.3 5 v power supply
GND Connect power negative
DO TTL switch signal output
AO This module does not work

The module do not have Analog output.
