Sensor Module with Sharp GP2Y0D810Z0F Digital Distance (5 cm)

Overview

These sensors are a great way to quickly detect the presence of nearby objects. It consists of a Sharp GP2Y0D805, GP2Y0D810, or GP2Y0D815 sensor module installed on our tiny carrier board for these sensors, which includes all of the external components required to make them work. The available versions offer three different sensing ranges:

• Carrier with GP2Y0D805Z0F: 0.5 cm to 5 cm

• Carrier with GP2Y0D810Z0F: 2 cm to 10 cm

• Carrier with GP2Y0D815Z0F: 0.5 cm to 15 cm

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, GP2Y0D810, or GP2Y0D815 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. With the LED in the circuit, the low output signal will be around 1 V. 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, in which case the low voltage will be below 0.6 V.

The GP2Y0D805, GP2Y0D810, and GP2Y0D815 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 or M2 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.
