Arduino Life 2: Getting Geeky in the Garden: Temperature, Humidity and Light Level Sensor [Video] (20:21)
I dive into the Arduino world and learn a lot in my first project, a temperature, humidity and light level sensor for my mini-greenhouse that also reports via SSH iOS notifications and Twitter and logs data to local SD Card and a Google Spreadsheet.
- Greenhouse Temperature, Humidity and Light Level Arduino Project
- Powered by USB power bank
- Arduino Yun connected to breadboard for power and sensor data
- Local WiFi connection via Arduino Yun for data reporting
- Read Temperature and Humidity using blue sensor at top
- Read current light level using photo-resistor and converting to 100 point scale (0-100, with 0 being total darkness)
- Date and Time pulled from Linux side of Arduino Yun
- Data logged to file on internal SD Card on Arduino (can be accessed remotely via SSH)
- Data logged remotely to Google Spreadsheet via IFTTT
- Data tweeted out to @douglaswelch via IFTTT
- Data notified on iPhone via IFTTT
- Currently polling and reporting every 5 minutes
- DOWNLOAD CODE for this project
