Motor Wheel Encoder Speed Sensor 3.3V-5V Slot-Type Optocoupler Counter Module

HC-020K FC-33 F249 Smartcar car 5mm 5 mm

mini 3-pin
PARAMETERSChip used: 74HC14D
Working voltage: 3.3V – 5V
Output mode: digital signal (pulse signal)Detection method: Infrared ray interruption
Detection signal: high level when an obstacle is detected, low level output when there is noobstacle or beyond the detection range.
LED: Two-way Status indicator, the ray interruption indicator is off, and the ray continuityindicator is on.
WIRING
1.+5V: lt is the positive input port of the power supply, which can be connected to a voltageof 3.3V~5V
2.GND: is the negative input port of the power supply
3.OUT: It is a signal output port, which is connected to the lO port of the MCU, generallyconnected to an external interrupt

3-pin FC-33
MODULE FEATURES
1, using imported slot type optocoupler sensor2.The groove width is 10mm.
3.There is an output status indicator, the output high level light is off, and the output lowlevel light is on.
4, there is occlusion, output high level:no occlusion, output low level.
5, the comparator output, the signal is clean the waveform is good, the driving ability isstrong, more than 15mA.
6, working voltage 3.3v-5V
7 , output form: digital switch output (0 and 1)
8, with fixed bolt holes for easy installation9, small board PCB size: 2.3cmx2cm10.Use a wide voltage LM393 comparator

MODULE INSTRUCTIONS
1. When there is no occlusion in the module slot, the receiving tube is turned on, and themodule D0 outputs a low level. When occluding, the Do outputs a high level;
2.The module DO can be connected to the relay to form a limit switch and other functions.lt can also be connected to the active buzzer module to form an alarm.

4-pin
MODULE 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-5
6, the output format: digital switching output (0 and 1y7, a fixed bolt holes for easy installation
8, small PCB board size: 3.2cm x 1.4cm9, using a wide voltage comparator LM393

MODULE FOR USE
1. module slot unobstructed, receiver tube conduction module DO output low, when blocked,DO output high;
2, D0 output interface can be directly connected to the microcontroller lO port, whether thesensor with barriers, such as the motor speed can be detected with the motor encoder.2.DO module can be connected to relays, limit switches and other functional composition,and to be connected with active buzzer module, consisting of alarm.

PRODUCT WIRING INSTRUCTIONS
1, VCC positive power supply 3.3-5V
2,GND power supply is negative
3, DO TTL switching signal output
4,AO not connect
