hi.. i would like to ask, is it i directly connect the output signal to the meter like above, then i will get the reading? or i need to change it to dc 1st onie can get the voltage like the video? pls help… thanks alot

Does anybody know how to connect a Sharp IRDM gp2y0a710k0f to an analog input of a Velleman k8055?

I got one of these a few weeks ago, but haven’t played with it yet. 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. Looking for to experimenting with this!

@SchrodingersCat (don’t know if you’re there or not :-))

You might look at the Maxbotix ultrasonic rangers which are $30. They’ll use more power though. They almost have to, as infrared is as power-frugal as you’re going to get at that range, as neither capacitive nor inductive sensing will work except in REALLY constrained environments.

accurate at distances from 0-80cm
maybe
parking sensor ..? but they expensive

I have used these sensors for a project of mine but found their accuracy (even after calibration) to be a bit off. The output even with the capacitor was very noisy. Does anybody know of another (preferable cheap) sensor that can do the same job but be more accurate at distances from 0-80cm?

I used these sensors for a microprocessor project. 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).

So I used them to measure the distance from the head, then controlled the motors in the head to look around and draw a ‘picture’ of the distances in front of it.

@DarkAxi0m
you’ll probably have to go with sonic or laser range finders for that kind of distance (re: golf range finders are typically laser).

The object used in the video is the “hack a day webserver on a businesscard” pcb ;)

I used three of these little sharp sensors for my masters project, a light weight height sensor for helicopter UAVs. I combined the GP2D15A, GP2A2YK and GP2AKOF in complement using a TI MSP430 to get a range from 15cm to about 5m. They are slightly tricky to use though since the output voltage isnt linear. Have a look if you like:

You’re right ethan and therian, this isn’t a hack. I notice that myself right off, when the title started with “Parts:” . . .

As long as there’s at least one hack per day the site can keep it’s name and it’s nice for them to post these little additions that might spark someones creativity and prompt a future hack.

well Ethan have a point, well here future hacks:
“termoresistor multimeter and a match”
“LDR and flashlight”
and everyone’s favorite touch activated a “button and a led”

@vonskippy – Sorry about the video quality on this one. It looked much better before being youtubeized.

Great video – I’m guessing the meter actually shows something eh?
