Intelligently irrigate your yard or garden with dynamic water cycles, rain detection, sunrise detection, and when it's warm enough.
Intelligently reduce the moisture in your basement/crawlspace to help control mildew growth and lower your heating/cooling bill.
Achieve up to 60% saving on program memory space using Shox96 Guaranteed Text Compression Library for Arduino Uno and upwards.

In standby mode the IO Expander only uses 37.6mA with 12V, but if you have 5V only 11mA. The IO Expander was designed to run in Hydroponics/Aquaponics systems that need to run off the grid, so yes it should work on a 12V panel with a battery.
It makes it a whole lot easier using the IO Expander and takes a lot less code space on the Arduino since all the sensor drivers are written in the IO Expander.
