Speed Measuring Sensor Groove Coupler Module For Arduino

This is Speed Measuring Sensor Groove Coupler Module For Arduino. This can be directly connected to a micro-controller/Arduino IO port if there is a block detection sensor, like speed of the motor encoder can detect. Wiring Specification : VCC:  positive 3.3-5 v power supply. GND: power negative. DO: should be use to get TTL signal output. AO: Should be used to get analog output. Package Includes : 1 x Speed Measuring Sensor Groove Coupler Module For Arduino.
