I have a howto question…first time working with sound sensors. So kindly indulge my ignorance.
I have the ADMP401 hooked up to a machine tool (dont ask why..) via an Xbee module. I am powering the sensor and Xbee with a li-poly 3.7 V 1000 mAhr supply. The output is being read into Matlab. Did the same thing with the ADXL335 accelerometer before worked like a charm.
Now with the sound sensor, how am I to take the raw ADC'ed signal and convert to sound on matlab. In all, the reading that comes out is in mV, how do you go from mV to dB for this device so I can hear the machine ‘talk’ to me.
No public wish lists :(
