humidity, and light quality/quantity
Ron, I just finished a system that monitors pH, temperature, humidity, and light quality/quantity. I will be using this to monitor you 11 plant garden that I constructed. The unit hooks up to your computers parallel port and can be set up to log the results over time. The results can then be viewed on an easy to read graph. The system can be used to sample every hour and show the results over a long duration. As well you can set minimum and maximum levels for each variable and have the data logger set off an alarm when they hit the preset limits. So for example you can set your pH level and wait until the alarm goes off to adjust your solution. I think this would work very well for hydroponics growers. The whole thing is very cheap, if you or anyone else is interested just email me at thesteeds@telus.net .
