Proximity sensors

Hello!

I hope I can write what I´m looking for in english… ;-)

My idea is to control max/msp with proximity sensors. I mean: if I move my hand to this sensors they send a message to a interface and it transforms this message into MIDI messages. I would like it be sensible to my proximity (values sent change if I move my hand to or from the sensor) Any idea of what I need for this? Oh, and I forgot: not too much expensive ;-)

I hope I have explained well…

Thanks and best regards!

Oh, I forgot it: I need it be easy to use ;-)

Thank you!

Hello ! Tu es français ? A good solution is ultrasonic sensor !

There are a number of sensor systems on the market that will work with MaxMSP and various types of sensors (motion, distance, temperature, etc.). The cheap and easy solution would likely be an Arduino (or equivalent) with some sort of IR distance sensor. You can find suitable sensors from a number of vendors, and there are lots of resources online (including the archives of this forum) for the Arduino. Good luck and have fun!

Thanks to both of you.

Stouf, I don´t speak french, so I´m not sure if that is what I´m looking for (google translate is not very good for that page)

Steven, I know these sensors, but what I need is the interface that transform their message into MIDI messages. And I don´t know anything about electronic hardware, so I need it be very simple to use.

Thank you and best regards.

The basic concept of your project is to convert the ANALOG signals, from sensors, into DIGITAL data that the software on your computer will recognise.

The sensors will connect to a microprocessor board (like Arduino or Make), which will use a small simple program to collect, translate and output the sensor data.

It is possible to do this without MaxMSP, so that the system will directly output MIDI data, but from the tone of your post this might represent a steep learning curve. There is a system from Eowave

but you might find the price higher than the solutions above; if you don’t have MaxMSP already it will cost $250-600; Arduino is around $30, and proximity sensors are very inexpensive. This means you might find the Eobody system of a comparable price.

This is a very good resource if you want to build your own:

Thanks to both of you. USB-MicroDig seems to be what I´m looking for:

But if anybody knows it and think it´s not, please advice me :-)

And what sensors would be what I need? There is a lot of them!

Thank you very much and best regards.

MIDItron is also worth a look
