5VDC Infrared Light Beam Counter Photoelectric Sensor Module N3 RPM Sensor
This module is a high-quality infrared counter module. It is very cheap in price. It comes with a small size and an integrated LM 393 chip. it is widely used in motor speed detection, pulse count, position limit.
It is using an imported groove optical coupling sensor and its width is 5mm.
It has an output in state light. If the output is on a high level, the light is off.
If the output is at a low level then the light is ON.
The output will be at a high level if it will be covered. And otherwise, its output level will low.
It has a good signal and waveform. It has a strong driving ability for more than 15mA.
It works on 3.3V to 5V.
It has a digital switch output of 0 and 1.
It is equipped with a fixed bolt hole and it is easily installed.
Its PCB size is 3.2cm x 1.4cm.
We can use LM393 wide voltage comparer.
Specifications of FC-33 10mm Arduino RPM Sensor Rotational Speed Measuring Sensor:
Its VCC connects to the positive 3.3 or 5V power supply.
Its GND connect to the ground pin.
Its Do pin is TTL switch signal output.
Its A0 pin is not working.
D0 data output interface can be directly connected to the microcontroller input-output port.
If we block the detection sensor, then the speed of the motor encoder can be detected.
This D0 module can be connected to the relay, limit switch, and other functions.
It can also be connected with the active buzzer module.
We can compose alarm through this module.
Applications of Photoelectric Infrared Count Sensor:
It is widely used in motor speed detection.
It is also used in pulse count.
It is also used in the position limit.
