I stumbled upon this kit trying to find a parts list for this book: https://www.amazon.com/Make-Sensors-Hands-Monitoring-Raspberry/dp/1449368107
I might just buy it based on your write-up.
Still looking for all the parts needed for the book ( usually they tell you on the first few pages)
Take a look at this one: make: Sensors. Is that what you're after?
