The IR Reflect Click Board™ carries a GP2S700HCP reflective photo-interrupter and an on-board potentiometer. On this type of photo-interrupter, the infrared emitter and receiver are facing the same direction; the infrared beam from the emitter gets bounced back to the receiver when an object is placed within the detecting range of the sensor.
mikroBUS Interface
The IR Reflect Click Board™ communicates with the target board microcontroller through mikroBUS AN and INT pins (an on-board potentiometer sets the Interrupt threshold). Its designed to use either a 3.3V or 5V power supply.
