We have reached the end of this chapter, and achieved our target by building our own weather station. On this journey, we learned how to use weather APIs to collect data from the web based on location (city or state), then we learned about temperature and humidity sensors, and also integrated these with Raspberry Pi. Finally, we learned how to use Google sheets and how to update them programmatically.
Until now, we have only seen and learned how we can interface sensors to Raspberry Pi and send data from internet to server. In Chapter 5, Controlling the Pi, we will learn how we can control any device connected to raspberry remotely.
