Beam Photoelectric Sensor Electric Counter Module

Description:

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.

Features:

• 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.
