DIY Arduino ProMini data logger

DIY Arduino ProMini data logger

Ed Mallon blogged about his DIY ProMini data logger build:

Typical pro-mini loggers built with this design sleep at 0.25mA, before extra sensors are added. At that current draw, the logger should deliver approximately six months of operation on three brand new AA batteries with a 15min duty cycle; depending on sensor load.
