An Arduino sketch for monitoring your plants!

It will read air temperature, humidity, light level and soil moisture.

Built to work with these lovely doodads:

• SainSmart ST7735R 1.8" TFT LCD
• DHT11 Temperature/Humidity sensor
• wRobot 553518 Light Sensor
• Sunkee Soil Hygrometer

TODO (sorted by difficulty, ascending):

• Flash a message on the LCD when something needs adjustment (water me).
• Done. Write status in 10, 30 or 60-minute intervals to micro-SD.
• Done. Open/close the moisture sensor circuit at intervals to slow oxidation (and measure less frequently).
• Normalize the light and moisture values to a useful scale.
• Add a solenoid attached to a water bottle for self-watering.
