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. Lots of information like ping sonar sensor, distance, and ping sensor are explained in the datasheet.

Does anybody know of another preferable cheap sensor that can do the same job but be more accurate at distances from cm?
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 output is unreliable for extremely close objects, seen as the small hump between 5 and 10cm. Lots of info such as digital converter, distance sensor, and distance are explained inside the datasheet. Learn how your comment data is processed.
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. I used three of these little sharp sensors for my masters project, a light weight height sensor for helicopter UAVs. Cool stuff, handy for more complicated projects.

It looked much better before being youtubeized.
In the datasheet the reader can learn explanation such as converter, the voltage output, distances, and analog distance. For an exhaustive discussion of the various Sharp proximity sensors, check out the Sharp IR ranger information page at Arconame.
Gpd212 this one instead its cheaper:. Gp2d2 wrong link- that one has a range finder on it, but its not dedicated. Check out the parts posts you may have missed.
Email required Address never made public. The output even with the capacitor was very noisy. Inside the datasheet the reader can read info like dissipation current, distance output, signal processing circuit, and range. Have a look if you like:.

Parts: Analog distance sensors (Sharp GP2D12/2Y0A02) | Hackaday
Home About Contact Us. 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. Try this for a 2m — 3m range: Many things such as reflectance ratio, measurement, maximum ratings, design, and distance measuring are explained inside this datasheet.

Datasheet of Sharp GP2D12/GP2D15 Distance Measuring Sensor
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. You are commenting using your WordPress. K, so gp2d21 things are great, but for those who want something digital, might I recomend these guys: We powered the sensors with a 5volt dattasheet, as shown in the schematic above. Even more, this datasheet presents information around supply voltage, analog distance sensor, and sensor.
Notify me of new posts via email. This datasheet presents information related to measurement, distance measuring sensor, signal processing circuit, and distance measuring. Sharp GP2D12 and 2Y0A02 infrared rangers output a voltage proportionate to the distance of an object from the sensor. I have used these sensors for a project of mine but found their accuracy even after calibration to be a bit off. They are slightly tricky to use though since the output voltage isnt linear.
The Sharp GP2D12 is an analog distance sensor that uses infrared to detect an object between 10 cm and 80 cm away. Looking for to experimenting with this! Leave a Reply Cancel reply Your email address will not be published.
