	* Checked May 20, 2020 - after a heavy rainstorm the past few weeks, I found the tupperware cracked and the unit submerged in about an inch of water. All batteries are dead, although I do not think water reacted quickly with the lithium as I see no melting of the plastic case. After a wash in acetone and brake cleaner, most of the corrosion was removed, and I was able to power up the unit and retrieve the data out the serial port. The water first shorted the trigger pin for the wakeup, before apparently draining the batteries and causing the unit to reboot several times. Interestingly, at these times the on-board humidity sensor recorded "100.00%"		* Checked May 20, 2020 - after a heavy rainstorm the past few weeks, I found the tupperware cracked and the unit submerged in about an inch of water.

			* As of 2020-08-13, the unit is running on regular batteries indoors. The LEDs had stopped working after the board was submerged in water, but seems to have since dried out and started working again.
