CI4 Internet Of Things With MySQL Arduino Code

For Server Or Web Code visit this repository.

Im using HTTPS for communication device with server

Im modify code from example ESP8266HTTPClient/BasicHTTPSClient.ino

Library

General

- DHT (For Example in send data temperature and humidity to database)

For ESP8266 (already installed when installing ESP8266 board)

- ESP8266WiFi.h - ESP8266WiFiMulti.h - ESP8266HTTPClient.h - WiFiClientSecureBearSSL.h
