Internet of Things with ESP8266

Reading data from a digital sensor

In this last section of this chapter, we are going to connect a digital sensor to our ESP8266 chip, and read data from it. As an example, we will use a DHT11 sensor, which can be used to get ambient temperature and humidity.

You will need to get this component for this section, the DHT11 sensor (https://www.adafruit.com/products/386)

Let's now connect this sensor to your ESP8266:

1. First, place the sensor on the breadboard. Then, connect the first pin of the sensor to VCC, the second pin to pin 5 of the ESP8266, and the fourth pin of the sensor to GND.

   This is what it will look like at the end:
