1037 – SLOT TYPE IR OPTOCOUPLER SPEED SENSOR MODULE LM393 3.3V-5V
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
VCC: Connect the positive 3.3v5v
GND: Connect power negative
