One of the more popular choices of sensors includes those you use to observe weather. In this case, you’ll start out with a sensor that measures temperature, barometric pressure, and calculates the altitude based on sea level pressure. There’s a lot you learn with only those two measurements.
The sensor that you will use is the BMP280 ...
