Well, I'm no expert, but the DS2436 measures voltage in the 2.5V - 10V range. According to wikipedia, a single solar cell produces .4-.6V, but I think they are often put in series to generate higher voltages. The DS2436 will draw 5uA at standby, and 100uA when reading a voltage, which should effect your measurement too much. So my suggestion: The DS2436 has 3 pins: GND (to data line gnd and solar cell gnd) DQ (to data line) VDD (to solar cell Vout) If your solar cell produces lower voltages, look at the DS2438 or the DS2450. The DS2450 might be useful if you want to sample several voltages. Paul ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
