Reducing power consumption in micro SD card.
tapasxplore posted a topic in Energia - MSPI am using micro SD card to log reading from four force sensors connected to the microcontroller (MSP430G2553). Controller logs reading to the SD card every 15 minutes and goes to sleep. I am using 1000 mAh battery, which is lasting over a week. Is it possible to reduce the power consumption as to make it last over a month. (#) Even if the microcontroller is sleeping for 15 minute, SD card is continuously consuming power. (#) It takes couple of mA to write. Help with any suggestion to reduce to power consumption drastically. Schematic and code (attached). Code_D
