IR Photoelectric Encoder Sensor

IR Photoelectric Encoder Sensor is a very simple kit consisted of an optical beam sensor (op to switch, phototransistor) with the digital and analog output. It can be connected to any microcontroller via the 4-pin header (minimum 3-pin interface). IR Photoelectric Encoder Sensor can work with 3.3V to 5VDC, and gives a 0V and 5V(0r 3.3V) output on DO (digital output) pin. It provides a HIGH voltage output when the beam is blocked, and a 0V output when the beam is unblocked. Your microcontroller can simply read the 0-5-0V pulse train to determine whether the is obstacle blocking the sensor, and if you have a disc, speed detection can be achieved. Correlation photoelectric Infrared count slot sensor module is a high-quality infrared Counter module at a very cheap price which comes with tiny size and integrated LM 393 chip. The IR Photoelectric Encoder Sensor module includes two LEDs, one LED as power indicator and another LED is for digital output indicator. The module has two vertical columns with an IR LED on one column and a phototransistor on the other. Whenever the path between the IR LED and phototransistor is cut, the D0 pin goes high. IR Photoelectric Encoder Sensor widely used in motor speed detection, pulse count, the position limit, etc. 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. This IR speed module sensor with the comparator LM393, we can calculate the speed of rotation of the wheels of our robot.
