Sentieris’ new rack monitoring product line combines open source control with high-accuracy rack probes to ensure an end-to-end, low cost solution that is unique within the data center and controls world. Raspberry Pi-based means low cost controllers and ubiquitous availability. High resolution means no more than +5 - 10% of scale to ensure critical accuracy across temperature and humidity measurement. Unique daisy-chained probes guarantee ease of configurations and building integration systems without having to resort to aggregators, repeaters or home runs back to individual controllers. Finally, in an industry unique solution, the Sentieris Visual Sensor can be used standalone, in a controlled/controller configuration and/or daisy-chained across multiple configurations...you determine how much hardware you need and never worry about having to purchase expensive add-ons to control simple, environmental monitoring.
