Creating the temperature monitoring circuit

For this example, we will be reusing the DHT11/DHT22 temperature circuit we created in Chapter 9, Measuring Temperature, Humidity, and Light Levels.

Here is what we need to do:

1. Build the circuit illustrated in Figure 9.2.
2. Connect the data pin to GPIO 24 (in Chapter 9, Measuring Temperature, Humidity, and Light Levels, we used GPIO 21, but we will use GPIO 21 for a LED later in this chapter).

Once you have built your circuit, we can continue and build our first IFTTT Applet.
