I like the product and how easy is it to use them and making a tight grip on the wires

Let us know!
We'll try to match the price for you
Couldn't load pickup availability
The KY-010 Photo Interrupter module consists of an optical emitter/detector in the front and two resistors (1 k? and 33 ?) in the back. The sensor uses a beam of light between de emitter an detector to check if the path between both is being blocked by an opaque object.
Connect the power line (middle) and ground (left) to +5V and GND respectively. Connect signal (S) to pin 3 on the Arduino.
