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
