Hello Great Community
I'm working on a school project involving the use of a battery bank for solar system and I've just started learning Arduino. I've been searching the forum for similar projects an found 2 decent similar projects which are the
scooterputer http://www.janspace.com/b2evolution/arduino.php/2010/06/26/scooterputer and battery temp sensing - Sensors - Arduino Forum
What is this "battery monitor" thing and how does Kurt connect his batteries? I downloaded Kurt's code, and although I do have some programming experience I felt like I was in a maze! 
Well, I'm sure it'll will be alright after getting to know with Arduino, or so I hope.
What I want to do is to remotely monitor the battery voltage and temperature, send the data to a server/database and show it on a smartphone/tablet. Maybe add Ampere/Watt too if it's not too much time consuming. However I don't know I'm looking for, as in electronic parts or how/if I should make my own?
TODO:
Display the voltage in % capacity left so I'm unsure if I should measure volt, amp or watt. Send this information to a server over GSM. This device will be placed in an area with no internet connection.
HAVE:
- An Arduino Mega atm, but if necessary I can get others.
- Tinkerkit
- 24V / 100A/h battery bank
QUESTION:
- What do I need to monitor the battery voltage?
- Is the temp sensor DS18B20, used by Kurt, still good to use? I mean it's from 2010.
- Are there other communication methods other than GSM? Must be easy to send the data to the server.
If there still are unclear things, please tell me.
I appreciate your time and ideas. In advance thanks!
