IOT Based Boiler Industrial Automation Using Esp8266

Abstract -This research describes the development and coding of an IoT-based boiler industrial automation system which integrates ESP8266 NodeMCU microcontroller with Blynk platform for real-time monitoring along with control functionalities. The system depends on an HC-SR04 ultrasonic sensor and a DHT11 temperature sensor for measuring boiler temperature and water level in the boiler tank. The system activates buzzer alerts with simultaneous warning notifications in the Blynk application whenever each temperature exceeds 50°C or water level falls below 7cm.The connectivity used to transmit sensor data via Wi-Fi comes from an ESP8266 which provides smooth access to Blynk cloud-based server capabilities. Users gain access to remote key boiler parameter observation through the system which has the effect of minimizing human inspection along with improving operational safety and industrial efficiency. The developed prototype presents an affordable automation solution suitable for industrial applications which follows standards of smart factories in Industry.
