PROTOTYPE HARDWARE DESIGN AND SOFTWARE DEVELOPMENT OF PASSWORD CODED ESP32 WEB SERVER BASED HOME APPLIANCES CONTROLLING SYSTEM ACCESSIBLE FROM ANYWHERE USING NGROK SOFTWARE
Abstract
- Web server based appliances controlling system is mostly built up by using any microcontroller and Wi-Fi or Bluetooth module. The system can control appliances in the coverage range of Wi-Fi or Bluetooth, not from anywhere. To solve this, the controlling system which is accessible from anywhere with internet access is built up by using ESP32 and ngrok software. ESP 32 is connected to the local network and IP address is obtained. This IP is inserted to the terminal window of ngrok software and a uniform resources locator (URL) is obtained. For security purposes, the password coded program is developed by using “base64encode” software. Using this URL and password, the home appliances are monitored and controlled from anywhere with internet access in the world. The web server home page is created with HTML (hypertext markup language) and CSS (cascading style sheets) to control the devices as well as to express the current status of home appliances. The communication between a web server and clients takes place via Hypertext Transfer Protocol (HTTP). This system is useful to monitor the status of home appliances and to control the switch “on “and “off” of the devices from anywhere with internet access.
