Sharp GP2Y0D805Z0F Digital Distance Sensor 5cm

This small digital distance sensor detects objects between 0.5 cm and 5 cm (0.2″ and 2″) away. With its quick response time, small size, low current draw, and short minimum sensing distance, this sensor is a good choice for non-contact object detection, and its short minimum detection distance l...

Description

Sharp GP2Y0D805Z0F, GP2Y0D810Z0F, or GP2Y0D815Z0F digital distance sensor on a US quarter for size reference

Overview

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:

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 analogue 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:

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).

Alternative Sharp distance sensors

We carry several analogue Sharp distance sensors as well: the Sharp GP2Y0A51SK0F 2 – 15 cm, the Sharp GP2Y0A41SK0F 4 – 30 cm, the Sharp GP2Y0A21YK0F 10 – 80 cm, and the Sharp GP2Y0A02YK0F 20 – 150 cm. These analogue distance sensors have longer minimum detection distances and much slower response times than the GP2Y0D805, GP2Y0D810, and GP2Y0D815, but they can see farther and report the distance to the detected object rather than simply if an object is detected.

A variety of Sharp distance sensors. From left to right: GP2Y0A02, GP2Y0A21 or GP2Y0A41, GP2Y0A51, and GP2Y0D8xx

We also carry the newer Sharp GP2Y0A60SZ analogue distance sensor (10 – 150 cm), which outperforms the other analogue Sharp distance sensors in almost all respects, offering a low minimum detection distance, high maximum detection distance, wide 3 V output voltage differential, high 60 Hz sampling rate, operation down to 2.7 V, and optional enable control, all in a smaller package.

FAQs

This sensor isn’t behaving as I expect: I’m getting intermittent detection much farther than the maximum range of the sensor and it’s not detecting objects within the advertised detection range. What’s wrong?
Issues like this can be the result of power supply problems, especially since this sensor draws power in short, large bursts, so make sure your power supply is capable of delivering the necessary current. If you experience this problem, try adding a 10 µF or so capacitor across the sensor’s power and ground near the sensor; this compensates for an inadequate power supply and typically restores normal functionality.
