Encoder Sensor Module

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
