An Environmental Monitoring System (EMS) in automation is a crucial technology used to track and manage various environmental parameters in real-time. It involves a network of sensors and devices that monitor factors such as temperature, humidity, air quality, gas emissions, and other environmental conditions. By integrating these systems into automated processes, businesses can ensure compliance with environmental regulations, optimize energy usage, and improve operational efficiency. The system can trigger alerts or automatic adjustments based on predefined thresholds, offering enhanced control and responsiveness. EMS plays a significant role in industries such as manufacturing, agriculture, data centers, and smart buildings, where maintaining ideal environmental conditions is essential for both operational success and sustainability.
