Opto Coupler Encoder Sensor Module

SKU : A10026 This is a very simple kit consisted of an optical beam sensor (opto switch, phototransistor) with the digital and analog output. It can be connected to any microcontroller via the 4-pin header (minimum 3-pin interface). It 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. The module includes two LEDs, one LED as power indicator and another LED is for digital output indicator. Specification and Features: Operating Voltage: 3.3V to 5VDC Slot width: 5mm Output Signal: Analog and Digital output Digital output will be HIGH when something is within the Slot, blocking the sensor. Of course LOW when there is nothing in the slot. Direct connection to microcontroller PCB Dimension: 3.2cm x 1.4cm
