Environment Sensors

In this chapter, we will look at building a really simple weather station using the DHT11 temperature/humidity sensor and a raindrop sensor. While the previous chapter used the basic digital input, the DHT11 temperature sensor will give us the opportunity to use a third-party library, and the raindrop sensor will use an analog pin. We will also introduce a couple of handy functions that we can use.

In this chapter, you will learn:

  • How to add third-party libraries to a sketch
  • How to use the isnan() function
  • How to use the map() function
  • How to use the DHT11 temperature and humidity sensor
  • How to use a rain sensor
