Chapter 5: Humidity and Temperature Measurement

This chapter describes how to practically measure humidity and temperature in an environment, as well as how to connect specialized sensors to a microcontroller board. You will find out how to use the commonly used sensors DHT11 and LM35. In this chapter, you will gain valuable information regarding gaining data acquisition from a temperature and humidity sensor and a sensor module and how to display it to a user.

In this chapter, we are going to cover the following main topics:

Introducing the DHT11 humidity and temperature sensor module
Connecting the DHT11 and LM35 sensors to the microcontroller boards
Coding to get data from the sensor module
Showing the humidity and temperature data results on the serial port monitor

By the end of this chapter, you will have learned how to properly connect a DHT11 humidity and temperature sensor and an LM35 temperature sensor to the Curiosity Nano and Blue Pill microcontroller...
