Does anybody know of another preferable cheap sensor that can do the same job but be more accurate at distances from cm?
The Sharp GP2D12 is an analog distance sensor that uses infrared to detect an object between 10 cm and 80 cm away. The datasheet gives us info such as ultra It looked much better before being youtubeized.
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. This datasheet contains things around circuit, voltage daasheet, data, and analog. Try this for a 2m — 3m range: They basically took gpp2d12 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.

Sharp GP2D12 and 2Y0A02 infrared rangers output a voltage proportionate to the distance of an object from the sensor. Your email address will not be published. They are slightly tricky to use though since the output voltage isnt linear. This site uses Akismet to reduce spam.

Want to request a part post? You are commenting using your Facebook account. The output is unreliable for extremely close objects, seen as the small hump between 5 and 10cm. Home About Contact Us. Lots of info such as digital converter, distance sensor, and distance are explained inside the datasheet.
Check out the parts posts you may have missed. I used three of these little sharp sensors for my masters project, a light weight height sensor for helicopter UAVs. Fill in your details below or click an icon to log in: We connected the output directly to a multimeter set to measure voltage. 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 have used these sensors for a project of mine but found their accuracy even after calibration to be a bit off.
Lots of information like ping sonar sensor, distance, and ping sensor are explained in the datasheet. This datasheet presents information related to measurement, distance measuring sensor, signal processing circuit, and distance measuring. Cool stuff, handy for more complicated projects. Sorry wrong link- that one has a range finder on it, but its not dedicated.
Looking for to experimenting with this! Notify me of new posts via email. 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.
Below are grabbed from this datasheet:. 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.

Try this one instead its cheaper: Many things such as reflectance ratio, measurement, maximum ratings, design, and distance measuring are explained inside this datasheet. The output even with the capacitor was very noisy. I used these sensors for a microprocessor project. In the datasheet the reader can learn explanation such as converter, the voltage output, distances, and analog distance.
