Hydroponics Monitor Sketch

I have an Arduino Mega monitoring my hydroponics. It monitors air temperature and humidity, conductivity (for nutrient density) and PH. The information is displayed on a 16×2 LCD display and uploaded regularly to the a MySQL database via PHP.

Future plans for this project include control over the ciruclation pump operation and automatic addition of nutrients and PH up/down as well as control of the settings and device operation from the website/smartphone app.
