Compare Speed Measuring Sensor Counter Motor Tester Coupler Module Price

Application Widely used in motor speed detection pulse count the position limit etc Feature Using imported 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 1 x Speed Measuring Sensor Module
