Given how many sensors there are in the wild, there’s a lot to say about sensors. Some of the key points from the full video are:

• When to look for a library to support your sensor and when to just write a few lines of code to read it. [Discussed at the 3:00 mark]
• Thinking about sensors that return non-linear responses and how that might affect your code. [4:40]
• Detecting a human presence on a door mat. [6:00]
• Using a Geiger counter to measure radiation and generate random numbers. [8:14]
• Where to look for docs and code when you start working with an unfamiliar sensor. [11:30]
