Module 3.2: Temperature and Humidity Sensing

In Module 3.2, we get an overview of the temperature and humidity sensor we’ll be using for this course. We learn the basics of temperature and humidity measurement, how the sensor works, and how to install the Arduino library to access and control the sensor. After that, we do hands-on labs where we read the temperature and humidity, control the sensor from our command line, and then use the temperature and humidity data to control another device.
