Landau’s Data Dashboard has been developed to support monitoring and download of data collected continuously at remote locations. Initially developed for noise and vibration monitoring, Landau’s Data Dashboard can be customized for any application such as monitoring ground water levels or water containments, air quality and dust, and more. The dashboard system can be designed to operate off-grid through solar installations or through direct power. Landau’s data dashboard has been intentionally priced to be a highly competitive and cost-effective solution for remote monitoring.
