This small digital distance sensor detects objects between 0.5 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, close-proximity object detection, and our compact carrier PCB makes it easy to integrate into your project.
The GP2Y0D805 Sharp’s is one of the smallest and fastest distance sensors. Includes all of the external components required to make them work. The GP2Y0D805Z0F detects objects between 0.5 cm and 5 cm away from the sensor face. 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 sensor using a three-pin 0.1" connector, such as the included 3x1 straight male header strip and 3x1 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 3x1 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. Depending on your power source, you might notice an increase in performance by placing a large (>10 uF) capacitor between power and ground somewhere near the sensor.
A red LED on the back of the PCB lights when the output is low, indicating that the sensor is detecting something. If so desired, you can disable this LED by cutting the trace between it and the OUT pin where it is marked on the silkscreen or by desoldering the LED.
The GP2Y0D805 have an optional enable input that can be used to put the sensor into low-power mode. The Pololu carrier board connects this input to Vcc so that the sensor is always enabled, but you can solder a wire to the pad labeled “enable” on the back of the PCB if you want control over this input. Note that you will need to cut the trace that connects the enable line to Vcc on the PCB if you want to be able to disable the sensor. This trace is marked on the silkscreen, and there is a caret that indicates where we suggest you make the cut.
The carrier board has a 0.086" mounting hole for a #2 screw. You can make the module more compact by cutting or grinding off this portion of the PCB if you do not need the mounting hole.
