Proximity sensing is always handy for robotics applications, but this sensor could also be used for touchless switching etc. It has built-in I2C connectivity making it compatible with most microcontrollers. Adafruit have also added a voltage regulator and level shifters to make it 3.3 to 5V logic and power compatible. Depending on your application, it's worth powering the board with 5V DC as this provides more power to its infra-red emitter for better illumination of nearby objects. Additional features include a visible light sensor and an interrupt output so that your microcontroller doesn't have to keep polling the sensor.\nSupplied as a fully assembled and tested proximity sensor board plus a strip of 0.1in. header pins for you to solder on as required. Adafruit provide working exam;
