Optical Interrupter Motor Speed Detection Sensor + Encoder for Arduino Robot 5pcs/set OSOYOO

1. Feature for LM393 Motor Speed Detection Sensor 

• Operating voltage: 3.3V-5V, output form: digital switching output (0 and 1)
• Mounting holes on both ends with M3 screws.
• Use:

1.  VCC is the positive input port of the power supply, which can be connected to a voltage of 3.3V~5V
2. GND is the negative input port of the power supply. 
3. OUT is the signal output port, which is connected to the I/O port of the single-chip microcomputer. Generally, it is connected to an external interrupt.

2. Acrylic Encoder
