GP2D12 Datasheet(PDF) – Sharp Electrionic Components

They are slightly tricky to use though since the output voltage isnt linear. The GP2D12 provides a non-linear voltage output in relation to the distance an object is from the sensor and interfaces easily using any analog to digital converter. I was thinking of replacing the transmit LED with a laser — I need to sense the distance of a small object at a distance, and a more-precise spot might be helpful. Have a look if you like:. Inside the datasheet the reader can read info like dissipation current, distance output, signal processing circuit, and range.

Try this for a 2m — 3m range: For an exhaustive discussion of the various Sharp proximity sensors, check out the Sharp IR ranger information page at Arconame. Looking for to experimenting with this! Try this one instead its cheaper: This graph shows the relationship between the output voltage of the GP2D12 and the distance of objects from the sensor datasheet page 3, figure 6.


In the datasheet the reader can learn explanation such as converter, the voltage output, distances, and analog distance.

Datasheet of Sharp GP2D12/GP2D15 Distance Measuring Sensor

They basically took the same sharp sensor and added their own really small pic microcontroller, and gave the things I2C out, or if you search around on their site they also have serial ones. I have used these sensors for a project of mine but found their accuracy even after calibration to be a bit off. Sharp GP2D12 and 2Y0A02 infrared rangers output a voltage proportionate to the distance of an object from the sensor.

The Sharp GP2D12 is an analog distance sensor that uses infrared to detect an object between 10 cm and 80 cm away. Sorry wrong link- that one has a range finder on it, but its not dedicated. I used three of these little sharp sensors for my masters project, a light weight height sensor for helicopter UAVs. Lots of information like ping sonar sensor, distance, and ping sensor are explained in the datasheet. We connected the output directly to a multimeter set to measure voltage.

Even more, this datasheet presents gp2c12 around supply voltage, analog distance sensor, and sensor. K, so these things are great, but for those who want something digital, might I recomend these guys: This datasheet presents information related to measurement, distance measuring sensor, signal processing circuit, and distance measuring.

Does anybody know of another preferable cheap sensor that can do the same job but be more accurate datadheet distances from cm? Fill in your details below or click an icon to log in: Please leave your suggestions in the comments.
