Arduino Greenhouse | WIZnet Makers

details

This Project is named “Arduino Greenhouse.”

The mega monitors indoor/outdoor humidity, temperature, soil moisture and light. I have targets set for humidity and temperature which i will be able to optimize after analyzing conditions vs growth. I hacked into a small humidifier from the local drug store to provide a source of moisture when it gets too dry. The fans both recycle air to keep the soil from staying too wet, and evacuate air to control temperature.

The data is visualized on the tft screen, and controls such as temperature, humidity, fan run times and various intervals can be set and saved to eeprom from the monitor.

The uno(slave) receives the sensor data and sends it to an instance of mysql running on amazons web service. This was the most recent development. Previously I was using plot.ly and was not pleased with the options/reliability. The thorough coverage by Charles Bell made this a breeze (http://drcharlesbell.blogspot.com/2014/02/announcing-mysql-connectorarduino-1.html). I was able to establish an instance of mysql and within 4 days I was able to insert sensor data from the arduino. I think that’s unbelievable! I can’t imagine what resources that would have taken 10 years ago.
