## Description

Application:Widely used in motor speed detection, pulse count, the 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.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.Specification: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 supplyGND Connect power negativeDO TTL switch signal outputAO This module does not workPackage included:5 x Speed Measuring Sensor ModuleThis is a perfect choice to make your project more interesting and vivid!If you have any questions, please feel free to contact us and we will answer your questions as soon as possible.
