Automated Food Gardener Ambient Condition Monitor

This project consists of the ambient condition monitor for the growing area.  The monitor will measure and record the following data:

1. Ambient Humidity
2. Ambient Temperature
3. Ambient Light

These measurements will be recorded, along with the time and date of the measurement.  The following design considerations must be addressed :

Measurement Frequency
Measurement Range
Measurement Accuracy
Power Consumption
Ease of expansion / future improvement

I’ll begin by looking at some of the hardware that I currently have available to see how suitable it is for this project. 

The hardware I currently have consists of an Arduino Nano,

a DHT22 Temperature and Humidity sensor

and a couple of Cds photoresistors.
