GP2D12 데이터시트(PDF) – Sharp Electrionic Components

Oompany is distribute Electronic parts in Iran market. 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: Does anybody know of another preferable cheap sensor that can do the same job but be more accurate at distances from cm? I used three of these little sharp sensors for my masters project, a light weight height sensor for helicopter UAVs. This datasheet presents information related to measurement, distance measuring sensor, signal processing circuit, and distance measuring.


Many things such as reflectance ratio, measurement, maximum ratings, design, and distance measuring are explained inside this datasheet.

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. This site uses Akismet to reduce spam.

Inside the datasheet the reader can read info like dissipation current, distance output, signal processing circuit, and range. In the datasheet the reader can learn explanation such as converter, the voltage output, distances, and analog distance. Try this for a 2m — 3m range: Lots of information like ping sonar sensor, distance, and ping sensor are explained in the datasheet.

Sorry wrong link- that one has a range finder on it, but its not dedicated. The datasheet datqsheet us info such as ultra Cool stuff, handy for more complicated projects. I have used these sensors for a project of mine but found their accuracy even after calibration to be a bit off. Try this one instead its cheaper: We connected the output directly to a multimeter set to measure voltage. You are commenting using your Facebook account. Looking for to experimenting with this!

I used these sensors for a microprocessor project. Learn how your comment data is processed.

Gp2r12 a look if you like:. 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. You are commenting using your WordPress. 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.
