10mm Arduino RPM Sensor Rotational Speed Measuring Sensor



the signal output indication
2,single-way signal output
3, output effective signal is low level
4,sensitivity non-adjustable
5, can be used to Workpiece count and Motor speed detect
6, Circuit board outputs switch quantity

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
