This sketch is for a device that measures temperature and humidity.
It uses the following products:
It is one part of a larger STEM lesson plan around composting and computer science.
See also the companion web application called weathervane and and 5 minute composting lesson.
Thanks to Adafruit and Jonathan Oxer for their libraries and examples, and Open Home Automations for their wifi-weather example.
Please feel free to improve the Compost Monitor Sketch, or any other part of the lesson plan.
Here are a few things I'd like to eventually add to do to the device, not just the sketch.
- Use a power source that is not your computer
- Use a sensor the can be submerged longer than an hour
- Alternative ways besides Wifi network to send data
- Design a case for the circuit
- Find and use cheaper materials
