We connected the output directly to a multimeter set to measure voltage.
Learn how your comment data is processed. I have used these sensors for a project of mine but found their accuracy even after calibration to be a bit off. 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. The output gpd212 with the capacitor was very noisy.
I was thinking gp21d2 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. Try this one instead its cheaper: Does anybody know of another preferable cheap sensor that can do the same job but be more accurate at distances from cm? Try this for a 2m — 3m range: In the gp2dd12 the reader can learn explanation such as converter, the voltage output, distances, and analog distance.
It looked much better before being youtubeized. There are lots of things around analog distance sensor, distance sensor, and distance sensors are explained in this datasheet.

We powered the sensors with a 5volt supply, as shown in the schematic above. The output is unreliable for extremely close objects, seen as the small hump between 5 and 10cm. Notify me of new posts via email. Even more, this datasheet presents information around supply voltage, analog distance sensor, and sensor. Please leave your suggestions in the comments. K, so these things are great, but for those who want something digital, might I recomend these guys: This datasheet contains things around circuit, voltage output, data, and analog.
I attached them to the head of a roboquad and then used them I fried the original IR sensor since I didnt know what it was. Sorry wrong link- that one has a range finder on it, but its not dedicated.
Check out the parts posts you may have missed. Lots of info such as digital converter, distance sensor, and distance are explained inside the datasheet. Inside the datasheet the reader can read info like dissipation current, distance output, signal processing circuit, and range. Want to request a part post? Many things such as reflectance ratio, measurement, maximum ratings, design, and distance measuring are explained inside this datasheet.

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.
You are commenting using your Twitter account. Sharp GP2D12 and 2Y0A02 infrared rangers output a voltage proportionate to the distance of an object from the sensor. Leave a Reply Cancel reply Your email address will not be published.
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. The datasheet gives us info such as ultra I used these sensors for a microprocessor project.
