Help with 1PCS Sound detection sensor module

Hi,

I have this Sound detection module :
http://www.ebay.com/itm/261083086582?ru=http%3A%2F%2Fwww.ebay.com%2Fsch%2Fi.html%3F_from%3DR40%26_sacat%3D0%26_nkw%3D261083086582%26_rdc%3D1

And this is the .pdf of the main chip:

I need help to connect this to a Basic Stamp2sx and create a code for this.
Please if someone could help me, Thanks.

The output goes low when it detects sound...

DO
  IF in0=0 THEN
    DEBUG CR,"I hear music"
    DO : LOOP UNTIL in0=1
  ENDIF
LOOP

Did the board come with documentation? It may need a pullup resistor at the output, because the LM393 pulls low but not actively high. The adjustment probably affects the threshold sound level.

Thanks Allen,

It worked fine, but I had to modify it a bit.

DO
  IF in0=1 THEN 
   DEBUG CR,"I hear music" 
   PAUSE 50 
   DO : LOOP UNTIL in0=0 
 ENDIF
LOOP

I have some questions, ¿Can it give another type of values other then just 0 and 1? ,if it do,
¿What comands could I use?,
¿Could I use something like SERIN o PULSIN?

Thanks.

By all indications, all it can do is 0 or 1. I don't have one, but everything it can do should be listed on its instructions sheet!

Ok.

Thanks Allen. :thumb:
