Working with Pressure, Humidity, and Temperature Sensors

After working with the GPS and SD card to continuously record data over time, we can now start exploring sensors that record weather data. This chapter focuses on using barometric, humidity, and temperature sensors with the Arduino board. Although there are many such sensors on the market, we will use several high-quality yet inexpensive sensors from Adafruit ( https://www.adafruit.com/ ). These sensors are easy to work with, and we will demonstrate how to use them individually before integrating them with the GPS data recorder in the next chapter.
