Encoder Sensor Module
- Brands China Code: SN-ENC-MOD
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.
