Product type
MEMS accelerometers are miniature devices that measure acceleration forces in one or more axes, often utilizing micro-electromechanical systems technology. They are typically made from silicon and can detect changes in motion or orientation with high precision. These sensors convert mechanical motion into electrical signals, enabling various applications in consumer electronics, automotive systems, and industrial machinery.
