I need to find a low cost system with simple development software I can work with.I need a battery powered system for remote tank level of a 0-5v analog sensor drawing 25 milliamps of power and requires 5 vdc power.I also need to develop a simple irrigation pump start stop controlled by SMS, possible built in Web server to monitor I/O and make modifications, see the current temperature, current tank level I/O status and sens SMS message to warn before freeze.
