I am working with the mda300 and mica2. I have attached an external ph sensor
to the differential channel 11 (A0 and A1) and grounded it at firt GND pin on
J6 of the mda300 board. I have downloaded onto my motes XMDA300_433_lp and am
using the crossbow Stargate and postgres database to store my data. When I view
my data from the stargate in Hyperterminal, I get the following readings:
Insert into mda300_results(result_time, nodeid, parent, voltage, humid,
humtemp, adc0, adc1, adc2, digi0, digi1, digi2) values (now(), 1, 0, 425, 829,
6679, 252, 0, 524, 0, 0, 0).
I want to know why I am getting readings on adc0, adc1, and adc2. And how is my
pin configuration and external sensor wiring configuration related to these
channels and the reading that I am getting. I need to convert the data I am
getting to ph readings.
Thank you.
