How Does It Work?

1. Data Collection: Sensors attached to machinery collect data on various parameters such as temperature, vibration, pressure, and humidity.
2. Data Transmission: The collected data is transmitted to a central system via IoT networks.
3. Data Analysis: Advanced analytics and machine learning algorithms analyze the data to identify patterns and anomalies.
4. Predictive Alerts: The system generates alerts when it detects signs of potential failure, allowing maintenance teams to take corrective action.
5. Maintenance Scheduling: Maintenance is scheduled based on the predictive insights, ensuring minimal disruption to operations.
