This is Speed Measuring Sensor Groove Coupler Module For Arduino. 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. Widely used in motor speed detection, pulse count, the position limit, etc.
Wiring Specification :
- VCC:Â The positive 3.3-5 v power supply.
- GND:Â Connect power negative.
- DO:Â TTL switch signal output.
- AO: This is analog output.
Technical Specifications:
- Using imported groove optical coupling sensor, width 5mm.
