Hi,
I'm running the Henriksen 1-wire weather station (wx.sandbox.org) and am experiencing problems with a humidity sensor. This sensor is daisy chained with the Dallas wind/rain/direction gauge, and they are all about 100' from the hub. I've noticed quite a few times that the weather s/w will get into a state of 100% CPU usage, and stops updating. When I look at my logs, I see the following just before it locks up:
05.03.2007 13:51:52 Humidity D70000007D833526: Volt supply below 4.0V (3.7), skipping!

05.03.2007 13:53:08 Humidity D70000007D833526: 10 errors reading Outside H: MLAN OK
10 consequtive errors, then locks up. I know it's a s/w problem, but Henriksen doesn't update his s/w anymore, so I'm trying to figure out why the sensor has a voltage drop spike, as this is what seems to lock up the reading of the sensor. This humidity sensor has it own local 5V regulator, as well as the BAT54C shocttky clamping diode, so I don't understand why it's getting a voltage sag. Has anyone have similiar problems? Thanks!
