I need suggestions on what kinds of systems are available to implement an environmental control system for an aquarium that would be accessable via a wireless 802.11 connection. Im just looking to control a light (on/off) measure and control the water temp.
dallas semi has some serial controlled switches, 24bit address, you just send a data stream out to the device and it switches. temperature measuring is simple as a probe and an adc, connect it to a digitally controlled pwm controller with an ultra slow clock and you have temperature control. you could do the same with an 8 pin PIC, a few hours of learnin, and building a simple programmer(noppp for instance).

not sure if this is what you're looking for but you might try the Lantronix Wi-Port
It pretty much converts a serial connection to a TCP/IP connection accessible via 802.11
Hope that helps.
