Modern industries operate in environments where factors such as hazardous gases, high temperatures, humidity variations, and machine vibrations can directly affect worker safety and equipment performance. Continuous monitoring of these parameters is essential to prevent accidents, reduce equipment damage, and ensure smooth industrial operation. However, traditional monitoring methods mainly depend onmanual inspection or basic control systems, which are time- consuming, less accurate, and unable to provide real-time remote access. These limitations can delay fault detection and increase the risk of industrial hazards. To overcome these issues, this project proposes a human-centered and cost effective IoT-based Industrial SCADA (Supervisory Control and Data Acquisition) system for real-time monitoring andautomated alerts. The system uses multiple sensors such as the MQ7 sensor to detect carbon monoxide, the MQ6 sensor toidentifycombustible gases, the DHT11 sensor to measure temperature and humidity, and a vibration sensor to monitor abnormalmachine movements. These sensors continuously collect datafrom the industrial environment and send it to the NodeMCUmicrocontroller, which acts as the main processing and communication unit. The NodeMCU transmits the collecteddata to the ThingSpeak cloud platform through Wi-Fi,allowing users to monitor the system remotely using graphsand dashboards. This helps operators understandenvironmental conditions clearly and take timely action whenrequired.Keywords: Io T , SCADA, Node MCU, IndustrialMonitoring, Thing Speak c l oud, GSM Alerts, GasSensor, DHT 11 , MQ 6 & 7 , Flamesensor , VibrationSensor.
