Speed Measuring Sensor


  • using imported trough type optical coupling sensor, groove width 5 mm.
  • the output state light, lamp output level, the output low level light.
  • covered, output high level;Without sunscreen, the output low level.
  • the comparator output, signal clean, good waveform, driving ability is strong, for more than 15 ma.
  • the working voltage of 3.3 V to 5 V
  • output form: digital switch output (0 and 1)
  • a fixed bolt hole, convenient installation
  • small board PCB size: 3.2 cm x 1.4 cm
  • use the LM393 wide voltage comparator Module


  • The module without slot, the receiving tube conduction, module DO output low level, shade, the DO output high level;
  • the DO output interface can be directly connected to a microcontroller 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, can also with the active buzzer module, alarm.Product connection details:The positive 3.3-1, VCC power supply 5 v2, GND connect power cathode
