This walk-through will show you how to build a sensor to monitor your plant's environment and use Stats in Sound's ERC-20 app to turn this data into music, allowing you to listen to your plant's reaction to it's environment. For more information on this project, please visit www.statsinsound.org.uk. Below is a sample of music generated by the ERC-20 app, monitoring a happy healthy chilli plant.
You will need some basic experience with soldering, breadboarding and using the Arduino platform for this tutorial.
This particular instructable is for a sensor that will upload it's data via an Ethernet connection. Your plant will preferably be indoors. It's a bit cheaper and easier than the WIFI version, but if you're feeling adventurous, you can check out the WIFI version here.
To build a plant sensor, you will need the following:
] 1 x Arduino Ethernet
] 1 x FTDI > USB cable
] 1 x Ethernet Cable (Cat 5E patch)
] 1 x DHT22 Temperature + Humidity sensor
] 1 x LDR (Light dependent resistor)
] 2 x 10Kohm resistors
] 2 x Nails (Any nails will do for now, galvanized is best though)
] Plenty of hook up wire (single core wire)
] A Soldering iron & plenty of solder
] A Mac or windows computer
We have provided links to some of the trickier parts to find.
Once you think you have everything, you can continue to the next step to get started!
