Sorry wrong link- that one has a range finder on it, but its not dedicated. 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 at distances from cm? They basically took g;2d12 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.
Try this one instead its cheaper:.
I used three of these little sharp sensors for my masters project, a light weight height sensor for helicopter UAVs. K, so these things are great, but for those who want something digital, might I recomend these guys: We powered the sensors with a 5volt supply, as shown in the schematic above.

They are slightly tricky to use though since the output voltage isnt linear. We connected the output directly to a multimeter set to measure voltage. Your email address will not be published.

This datasheet contains things around circuit, voltage output, data, and analog. Below are grabbed from this datasheet:.
The Sharp GP2D12 is an analog distance sensor that uses infrared to detect an object between 10 cm and 80 cm away. I used these sensors for a microprocessor project. I have used these sensors for a project of mine but found their accuracy even after calibration to be a bit off. You are commenting dataaheet your WordPress.

Check out the parts posts you may have missed. 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. Even more, this datasheet presents information around supply voltage, analog distance sensor, and 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.

The output is unreliable for extremely close objects, seen as the small hump between 5 and 10cm. 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. It looked much better before being youtubeized. Dear SalesOompany is distribute Electronic parts in Iran market. Sharp GP2D12 and 2Y0A02 infrared rangers output a voltage proportionate to the distance of an object from the sensor.
