This small digital distance sensor detects objects between 2 cm and 10 cm (0.8″ and 4″) away. With its quick response time, small size, and low current draw, this sensor is a good choice for non-contact object detection.

These small and responsive sensors from Sharp are great way to quickly detect the presence of nearby objects. The available versions offer three different sensing ranges:

GP2Y0D805Z0F: 0.5 cm to 5 cm

GP2Y0D810Z0F: 2 cm to 10 cm

GP2Y0D815Z0F: 0.5 cm to 15 cm

There are a few millimeters of hysteresis around the maximum range threshold and no hysteresis at the minimum range threshold. Note that these sensors will only tell you if there is an object within the detection range along their lines of sight; they will not tell you how far away the object is.

With a detection distances up to 150 mm and a typical sampling rate of almost 400 Hz, these sensors provides attractive alternatives to shorter-range LED-phototransistor reflectance pairs and longer-range but slower sensors such as the Sharp GP2Y0A41SK0F analog distance sensor. The output, Vo, is driven low when the sensor detects an object; otherwise, the output is high.

Please note that 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 a carrier board for this sensor that makes it much easier to use by including these required components and providing a 0.1″-pitch, three-pin interface: ground, power, and digital output. The carrier board is available with these sensors pre-installed:

with the 5 cm GP2Y0D805Z0F

with the 10 cm GP2Y0D810Z0F

with the 15 cm GP2Y0D815Z0F

Alternatively, you can order the carrier board without any sensor and solder one in yourself. The pictures below show our bare carrier board (left) and the carrier board with the Sharp digital distance sensor installed (right).
