There is a new industry creating low-power bluetooth sensors that run for
months off a CR2032 or AAA battery.  Parrot (French company that also makes
UAV's) makes a light+temperature+moisture sensor for plants.
http://www.elinux.org/RPi_Bluetooth_LE discusses Bluetooth LE, but with
wireless you might be able to record
data on a system located in a secure area.

Tessle.io has a modular USB-based system with a range of sensors with linux
support, including an "ambient" sensor for light and sound.
