This work presents the development of a low-power wireless triaxial accelerometer designed by Lind Engineering for Structural Health Monitoring (SHM). Its goal is to provide a nationally manufactured, cost-effective technology with capabilities comparable to high-end international systems. The project includes stages such as optimizing sampling frequency, integrating with commercial data acquisition systems, incorporating IoT communication, developing power supply hardware, and encapsulation at TRL 6. , for further validation within Lind clients. Current efforts focus on maximizing sampling frequency and configuring ranges of ±2 g, ±4 g, and ±8 g, essential for analyzing high-frequency vibrations in critical infrastructure such as bridges, railways, and mining facilities. Tests have reached up to 2000 Hz, exceeding the 125 Hz minimum target. The design is robust (IP67) and supports protocols such as FTP and SFTP, enabling integration with real-time visualization platforms. In summary, it is a scalable and cost-effective solution for structural monitoring of critical infrastructure.
