Line-up of distance output/distance judgement type. Distance output type (analog voltage): GP2D Detecting distance: 10 to 80cm. Distance judgement type. 25 May Introduction. GP2D12 The Sharp GP2D12 is an analog distance sensor that uses infrared to detect an object between 10 cm and 80 cm. In this small project we are going to use Sharp GP2D12 sensor and an Arduino Uno to measure the distance between the sensor and an object. You can use.

Arduino and community have made the programming much easier than ever before. Does anybody know of another preferable cheap sensor that can do the same job but be more accurate at distances from cm? The use of the GP2D12 with an Arduino is simple.

The output is unreliable for extremely close objects, seen as the small hump between 5 and 10cm. Please leave your suggestions in the comments.

Now you can watch the distance value in the window of Arduino The sensor sends out a beam of light and uses triangulation to measure the distance.
I found a extensive explanation on the Acroname website: Skip to content In this small project we are going to use Sharp GP2D12 sensor and an Hp2d12 Uno to measure the distance between the sensor and an object. Want to request a part post? This site uses Akismet to reduce spam. Looking for to experimenting with this! Please separate emails by comma.
Notify me of tp2d12 comments via email. I have used these sensors for a project of mine but found their accuracy even after calibration to be a bit off. It looked gp2d2 better before being youtubeized. Sharp GP2D12 and 2Y0A02 infrared rangers output a voltage proportionate to the distance of an object from the sensor.
We have to apply power and connect the output with an analog port of the Arduino. Have a look if you like:. You are commenting using your Facebook account. Check out the parts posts you may have missed.

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 even with the capacitor was very noisy. 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.
Fill in your details below or click an icon to log in: According to the official manual, it is known that the output of the GP2D12 is 0. By using our website and services, you expressly agree to the placement of our performance, functionality and advertising cookies.
To calculate the values from the analog port to a distance in cm a formula is needed. You are commenting using your WordPress. They are slightly tricky to use though since the output voltage isnt linear. In this small project we are going to use Sharp GP2D12 sensor and an Arduino Uno to measure the distance between the sensor and an object. The beam is 6 cm wide at 80 cm distance, so keep this in mind when using this sensor.
Try this for a 2m — 3m range: Maybe it is not yet convenient to make complex interfaces, but we can at least start from the most commonly used modules. These the breadboard-less firm connection are prepared to extensive modules like poteniometers, sensors, relays, servos Required Please separate emails by comma. In the image above you vp2d12 see that if anything is in the way of the beam the sensor will receive a reflection of the light.
I attached them to the head of a roboquad and then gp2r12 them I fried the original IR sensor since I didnt know what it was. This graph shows the relationship between the output voltage of gp2c12 GP2D12 and the distance of objects from the sensor datasheet page 3, figure 6. We can build electronics projects just as easy as piling bricks.
