Sharp’s distance sensors are a popular choice for many projects that require accurate distance measurements. This particular sensor is small and affordable, making it an attractive alternative to sonar rangefinders, while its wide sensing range and resistance to interference from ambient IR set it apart from other IR distance sensors. With an ability to measure distances from as close as four inches to as far as five feet (10 cm to 150 cm), this sensor has the widest range of any of our Sharp distance sensors, and its 60 Hz update rate is more than twice that of Sharp’s older GP2Y0A02YK0F analog distance sensor that has a similar sensing range.
However, this sensor requires external components and has a non-standard 1.5 mm pitch, which can make it difficult to integrate into projects based on a 0.1″ pitch. We offer two carrier boards for this sensor that make it much easier to use by including these required components and proficing a 0.1″-pitch, four-pin interface: ground, power, analog voltage output, and enable. The 5V carrier board, available by itself or with the sensor pre-installed, configures the sensor for 5V mode, with a recommended operating voltage of 2.7 V to 5.5 V; the 3V carrier board, also available by itself or with the sensor pre-installed, configures the sensor for 3V mode, with a recommended operating voltage range of 2.7 V to 3.6 V.
