Motor Speed Sensor Module
This is a speed sensor, the major goal is to check the rate of motor.
It was widely used in motor speed detection, pulse count, the position limit, etc.
Features:
Groove type optical coupling sensor
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 is clean, good waveform, driving ability is strong, for more than 15 ma.
has a fixed bolt hole, convenient installation
Specification:
Groove width 10 mm.
the working voltage of 3.3 V to 5 V
output form: digital switch output (0 and 1)
PCB size: 2.3 cmx2cm
use the LM393 wide voltage comparator
