Parts needed for an Arduino watering project?
I have a Uno R3 and a collection of relays, shields and parts but I'm not sure if there is task specific shields and things that would make it more efficient.
If I want a greenhouse watering system, do I need a stronger or multiple arduino?
It should sense the soil saturation, and when it falls below a certain level, start a water 12v water pump (200 mA draw) to pump water through driplines for a set amount of time (instead of soil sensor hitting a certain level to make sure plants at end of dripline get sufficient water). If I want it to be wireless, and in a remote location with no power sockets, would a 12v 5 Amp hour battery work as a power supply? I'm a beginner with Arduino so any help would be appreciated, especially with the wireless aspect (bluetooth, "wireless", or wifi?)? Thanks!
Oops, I forgot to add in that I wanted other sensors such as temperature, humidity, CO2 etc... so a wireless setup can transmit data back to my computer or I can remotely start the water pump when it's abnormally hot (which I guess I could automate with a temp sensor, but oh well). I found a transceiver module on ebay from china, but it's a one piece transceiver. Does it require another transciever to work or can it send data directly to a laptop?
