Overview
The compact HOBO MicroRX Station is an easy-to-deploy, low-cost cellular solution for long-term, reliable monitoring of indoor conditions in warehouses, cold storage facilities, data centers, museums, commercial and residential buildings, and more. The station includes an integrated HOBOnet Manager, for easy deployment with wireless HOBOnet sensors. The station also features inputs for up to five of Onset’s research-grade plug-and-play sensors. Configurable station-side alarms trigger immediate notifications of critical conditions, and Onset’s cloud-based HOBOlink platform makes it easy to view, access, and share data.
