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.

Calling API using ESP8266

The objective of this tutorial is to explain how to do HTTP JSON GET requests using an ESP8266 and Arduino IDE. Components Required ESP8266 USB Cable Hardware Connect ESP8266 to Computer   Software Code #include <ESP8266WiFi.h> #include <ESP8266HTTPClient.h> #include <ArduinoJson.h> const char* ssid = "SERVER NAME"; const char* password = "SERVER PASSWORD"; void setup() { Serial.begin(115200); WiFi.begin(ssid, password); while (WiFi.status() != WL_CONNECTED) { delay(1000); Serial.println("Connecting..."); } } void loop() { if (WiFi.status() == WL_CONNECTED) { ...
