Speed Measuring Counter Sensor Groove Coupler Module

This is a Speed Measuring Counter Sensor Groove Coupler Module, the major goal is to check the rate of motor. The DO output interface of this speed measuring sensor can be directly connected to a Arduino or any micro-controller IO port if there is a block detection sensor, such as the speed of the motor encoder can detect.

DO of Speed sensor modules can be connected to the relay, limit switch, and other functions, it can also with the active buzzer module, compose alarm. The module can be used in association with a microcontroller for motor speed detection, pulse count, position limit, etc.

Feature:

• Using imported groove optical coupling sensor, width 5mm
• It have 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 it output low level
• Good signal and waveform, with strong driving ability for more than 15mA
• Equipped with a fixed bolt hole, easily install
• Use the LM393 wide voltage comparer

Specification:

• Operating Voltage(VDC): 3.3 to 5
