Speed Measuring Sensor Counter Motor Test Groove Coupler Module For Arduino

Specifications:

• 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.
• DO modules can be connected to the relay, limit switch, and other functions, it can also with the active buzzer module, compose alarm

?

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

?

Descriptions:

• 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.
• The working voltage of 3.3V to 5V.
• Output: digital switch output (0 and 1).
• Equipped with a fixed bolt hole, easily install.
• Small board PCB size: 3.2 cm x 1.4 cm.
• Use the LM393 wide voltage comparer.

?

Application:

• Widely used in motor speed detection, pulse count, the position limit, etc
