MEMS (Micro-Electro-Mechanical Systems) sensors are compact devices that combine mechanical and electrical components at a microscopic scale. These sensors are designed to detect changes in physical conditions such as motion, pressure, temperature, and humidity. When integrated into IoT (Internet of Things) systems, MEMS sensors act as the primary data collection layer, enabling devices to sense and respond to real-world environments.
The development of MEMS technology emerged from the need to miniaturize traditional mechanical systems while maintaining high precision and reliability. With advancements in semiconductor fabrication, these sensors have become smaller, more efficient, and widely used across industries.
In IoT ecosystems, MEMS sensors are embedded in devices like smartphones, wearable gadgets, industrial machines, and smart home systems. They continuously gather data, which is then transmitted to cloud platforms or edge systems for analysis. This real-time data flow enables automation, monitoring, and intelligent decision-making.
