Arduino Bus PV Logger

SparkFun 9V Barrel Jack Adapter. S musing on technology: Arduino SD data logger with time stamp. I've been learning about powering my ham shack with solar power and have been working on logging battery voltage to get information about how my power budget is going.

At first I used an Arduino's A/D to read the voltage and periodically send it out the USB serial port, but as the shed has no mains power the laptop was a major drain on the battery itself. Yes, measuring was really altering the experiment. An SD Shield Plus, purchased via eBay, has all the things you need for stand alone data logging. Buy Microcontroller & Processor Arduino Wireless Shield with SD socket Arduino A000065 online from RS for next day delivery. Arduino Wireless Plug-in Module The Wireless Shield allows an Arduino board to communicate wirelessly using a wireless module.

It is based on the Xbee modules from Digi, but can use any module with the same footprint. The module can communicate up to 100feet indoors or 300feet outdoors (with line-of-sight). It can be used as a serial/USB replacement or you can put it into a command mode and configure it for a variety of broadcast and mesh networking options. Data Logging Shield for Arduino Data logging shield for arduino [ARSH-09-DL] - £13.33 .:oomlout:. A nice shield for fulfilling all your data logging needs.

Data can be stored to an SD card, while the on board real time clock (DS1307) allows you to time stamp your readings. An included prototyping area makes it easy to add extra circutry. It is a great shield to interface into any project using the well documented software libraries. Features: SD Card works with either FAT16 or FAT32 formatted cards (a 3.3v level shifter prevents damage to the card)On board battery keeps the time accurate even when your Arduino is un-poweredIncluded libraries make getting up and running a breeze.
