1814-PA1 – SLOT TYPE IR OPTOCOUPLER SPEED SENSOR MODULE LM393 3.3V-5V
to measure revolution per minute (RPM). It requires an encoder disc to
count the number of times the sensor goes low to high or vice versa we
can calculate the revolution in a given period of time. It has an analog
and digital output.
It is commonly used in robotics speed sensing printers and motor
drivers.
Main Chip: LM393
Output: Covered output high level; Without sunscreen the output low 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
modules can be connected to the relay limit switch and other
functions it can also with the active buzzer module compose alarm
VCC: Connect the positive 3.3v5v
GND: Connect power negative
