Future wireless sensing applications heavily depend on the analysis of wide-band channel state information (CSI) acquired from extremely dense device deployments. However, a gap exists in practical evaluations within existing literature. To bridge this gap, we introduce SensingWall, a highly adaptable, cost-effective solution leveraging IEEE 802.11 and the readily available ESP32 platform. SensingWall simplifies the process for application designers by abstracting away intricate technical details, offering visualization tools, and enabling direct access to a centralized database housing real-time CSI data. Our demonstration includes a functional prototype showcasing two key features. Firstly, real-time visualization of CSI time-series data from both uplink and downlink. Secondly, a demonstration of custom CSI retrieval through SQL-like query operations.
