Description
IR Sensor Enclosed Pair Long Leads. IR beam break sensors are a simple way to detect object present. They consist of an emitter of IR light and a receiver sensitive to that light. When an object passes between the two diodes a signal digital value 0 is sent down the yellow or white third wire. The third wire con be connected directly to any of our controllers or sound cards. Black is ground and red is +5V DC. This product is compatible with any Adifruit or Arduino lines of products.
