SPEED Measuring Sensor Module LM393 Gro-ove Motor Counter Coupler RPM Sensor Rotational Speed Measuring Sensor Module For Arduino Electrical Circuitry & Parts

Feature:

• Using imported groove optical coupling sensor, width 5mm.

• It has the output state light, if output high level, the lights are off. if output low level ,it on.

• If it covered, it will output high level; otherwise it output low level.

• Good signal and waveform, with strong driving ability for more than 15mA.

• The working voltage of 3.3V to 5V.

• Output: digital switch output (0 and 1).

• Equipped with a fixed bolt hole, easily install.

• Small board PCB size: 3.2 cm x 1.4 cm.

• Use the LM393 wide voltage comparer.

Instructions:

• The DO output interface can be directly connected to a micro-controller 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, it can also with the active buzzer module, compose alarm.

Wiring specification:

• VCC Connect the positive 3.3 5 v power supply

• GND Connect power negative

• DO TTL switch signal output

• AO This module does not work

Application:

• Widely used in motor speed detection, pulse count, the position limit, etc.

Package Includes:

• 1 x Speed Measuring Sensor Module LM393 Groove Motor Counter Coupler RPM Sensor Rotational Speed Measuring Sensor Module For Arduino
