Social Media Apps Controls Communication Devices Based on IoT

In this paper, a system for monitoring and controlling the operation of communication devices with low cost using a Telegram message based on the internet of things (IoT) is proposed and implemented. The ESP8266 Wi-fi module is working to connect the webserver gateway with the temperature sensor and remote-control system to turn on and off the devices. Then the temperature data is stored in the database of the server with information about the environmental conditions of the devices in the format real-time on the Android screen. The system alert will be sent to the responsible person if the temperature exceeds the permissible limit, which is the time required for transmission System alerts using the Telegram messenger, which takes about 6 to 7 seconds. The system also can self-start the cooling devices according to pre-programming or remote control using the application (Telegram or WhatsApp). The prototype is carried out using two high voltage relays, Arduino NodeMcu, and a temperature sensor. The outcomes obtained through the experiment process via the telegram messages have shown effective results.
