Hi All. I'm designing a computer to automate my garden. I'm looking for
input as to what it should do. At present, the design includes for each
plant:
a timer to start/stop watering
a soil moisture sensor to start/stop watering
a spectrum analyzer to look at plant colors
The unit will operate water valves and dispense fertilizer (probably built
in). The software will be different for different plants.
Any input will be appreciated. Thanks
Larry




Believe you meant the timer for the duration of watering.

The moisture sensor is the crux of on/off of the watering system. If it
goes bad and irrigation is not monitored personally, garden could either go
dry or be turned on/off in a radical manner producing flooding.

The reason I mention this if the user goes on a 2 week vacation elsewhere,
could be a major problem.
