In the market, there are many kinds of infrared distance measuring sensors. But if they connect
with Teleo board, we just need to consider if they are Digital In or Analog In.

As I know, the infrared distance measuring sensors we usually using for making wide range sound
effect is the “Analog In” infrared distance measuring sensors. Moreover,
I found there are two kinds of infrared distance measuring sensors.

Sharp GP2Y0A02YK IR Sensor (long distance)

Reports distance as an analog voltage with a range of ~8″-60″ (20cmx150cm)

Sharp GP2D12 IR Sensor (short distance)

Reports distance as an analog voltage with a range of 4″-30″ (10cm-80cm)

Value Setting in Max/MSP (Infrared Rangefinders)

Sharp GP2D120 IR Sensor (shortest distance)

Reports distance as an analog voltage with a range of 1.5″ to 12″ (4cm-30cm)

Ultrasonic Distance Measuring Sensor

Subject: Re: How to connect the ultrasonic distance measuring sensor to Teleo Intro Module?

“The 6500 Ranging Module’s output is a pulse. The timing of the pulse must be determined
very precisely to measure distance. The Mini A module has converted the distance
timing measure into an analog voltage, which can be measured by the Teleo AIN.”

In this experiment, I already tried my best to search several possible ways
to make the ultrasonic distance measuring sensor (6500 Ranging Module) compatible
with the Teleo Intro Module. Finally, I gave up because the two techincians
from Makingthings and Acroname cannot solve the technical problem and make the
same conclusion. The detailed e-mail discussions are in
10/28 of my Interaction Digital Diary blog.
