Installing DHT library on the ESP8266

As part of this activity we show you how to install the DHT library on the Arduino IDE. This will be used to allow your DHT11 sensor to communicate with your NodeMCM so that you can get the readings.

To read from the DHT sensor, we’ll use the DHT library from Adafruit. To use this library you also need to install the Adafruit Unified Sensor library. Follow the next steps to install those libraries.

1. Open your Arduino IDE and go to Sketch > Include Library > Manage Libraries. The Library Manager should open.

2. Search for “DHT” on the Search box and install the DHT library from Adafruit.
