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 (Micro-Electro-Mechanical Systems) technology emerged from the need to miniaturize traditional mechanical systems while maintaining high precision and reliability.
Advancements in semiconductor fabrication have made these sensors smaller, more efficient, and widely used across industries. In IoT ecosystems, MEMS sensors are embedded in devices such as smartphones, wearables, industrial machines, and smart home systems.
They continuously gather data, which is transmitted to cloud or edge systems for analysis, enabling automation, monitoring, and intelligent decision-making in real time.
