Sharp GP2Y0D805Z0F IR Range Sensor - 0.5cm to 5cm

Overview:

The GP2Y0D805 and GP2Y0D810 are Sharp’s smallest and fastest distance sensors, and our tiny

carrier board for these sensors includes all of the external components required to make them work.

With a sample rate of almost 400 Hz and a sensing distance to 5 cm (GP2Y0D805) or 10 cm

(GP2Y0D810), this sensor provides an attractive alternative to shorter-range LED-phototransistor

reflectance pairs and longer-range but slower sensors such as the Sharp GP2Y0A21YK0F analog

distance sensor. The output, Vo, is driven low when the sensor detects an object; otherwise, the output

is high.

The GP2Y0D805Z0F detects objects between 0.5 cm and 5 cm away from the sensor face, and the

GP2Y0D810Z0F detects objects between 2 cm and 10.25 cm away. 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.

Some example applications include:

• break-beam sensor or photogate alternative

• non-contact bumper or obstacle detector

• a counter or timer of objects as they pass by

Using the Sensor: The Pololu carrier board lets you interface with the GP2Y0D805 or GP2Y0D810 sensor using a threepin 0.1" connector, such as the included 3×1 straight male header strip and 3×1 right-angle male header strip. You can connect to these pins with a servo cable or with a custom-made cable using pre-crimped wires and a 3×1 crimp connector housing. The square pad is ground, the middle pad is VIN (2.7 – 6.2 V), and the remaining pad is the sensor output, OUT.
