High Quality 4 PIN IR Infrared Speed Sensor Module Groove Coupler Module For 3.3V-5V
Widely used in motor speed detection, pulse count, the position limit, etc.
The module features:
1, using imported trough type optical coupling sensor, groove width 5 mm.
2, the output state light, lamp output level, the output low level light.
3, covered, output high level;Without sunscreen, the output low level.
4, the comparator output, signal clean, good waveform, driving ability is strong, for more than 15 ma.
5, the working voltage of 3.3 V to 5 V
6, output form: digital switch output (0 and 1)
7, a fixed bolt hole, convenient installation
8, small board PCB size: 3.2 cm x 1.4 cm
9, use the LM393 wide voltage comparator Module
1. The module without slot, the receiving tube conduction, module DO output low level, shade, the DO output high level;
2, 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.
2. 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
3, DO TTL switch signal output4, AO the module does not workShipping list:A speed measuring sensor module
Working voltage: 3.3V~5V
5mm Groove width
Using wide voltage LM393 comparator
Output form: Digital switch output (0 and 1)
Sensing slots are blocked, the output high and the light is off; no shelter, output low and lights.
VCC: + power
GND: - power
DO: Digital Output
