	GRASS can be run non-interactively in text mode, without the GUI (see [[GRASS_and_Shell#GRASS_Batch_jobs\|GRASS Batch Jobs]]), and so beyond a simple datalogger your remote RPi can perform full data processing, creation of finished real-time maps ~~and~~ data plots, and serve via FTP or a web page running in the background. An ethernet connection, USB WiFi dongle or VHF radio packet modem can be connected to either push the data back to your home base, or stay online ready for queries.

	To save power, pair with a low power {{wikipedia\|Arduino}} board (like the ''Ultra Mini 8'') with a timer on it. You can have the system boot, perform a measurement, and send off the results, before shutting itself back down for another hour of <1mA sleep. In this way a small solar panel and a 6v or 12v sealed lead-acid battery (plus a 5v regulator) can keep the unit running indefinetly.

	The classic DIY field gear solution to this is to get a small Pelican Case, and drill some holes in the ~~lid~~ where you mount some waterproof bulkhead connector fittings with silicone sealant, or install pass-through cable glands. Make the power button a red light-up one with a {{wikipedia\|molly_guard}} to make it look professional. :o)		The classic DIY field gear solution to this is to get a small Pelican Case, and drill some holes in the side where you mount some waterproof bulkhead connector fittings with silicone sealant, or install pass-through cable glands.
