Interfacing DHT11 Sensor with ESP8266 - Practical Implementation

Interfacing DHT11 Sensor with ESP8266

In this article, I am going to explain about interfacing of DHT11 sensor with ESP8266. For that we have to make only 3 connections between the DHT11 sensor and ESP8266. For the working demonstration we will be programing ESP8266 as a web server for displaying temperature and humidity in a web browser as per request.
