Implementing a large scale sensor deployment for watershed assessment has previously been limited by the high cost of the datalogging and communication infrastructure. Stroud™ Water Research Center is overcoming the obstacles to large near-real-time data collection networks by using Arduino, an open source electronics platform. The open-source nature of Arduino means the cost is extremely low compared to similar commercial electronics options. By significantly decreasing the cost of the datalogging and communication hardware, resources can be focused on installing more sensors for greater spatial coverage.

We are sharing our experiences building wireless sensor networks in an online community, so that anyone can replicate and implement their own versions of our instrumentation. To follow our progress and share your experiences, visit

In June 2006 the National Oceanic and Atmospheric Administration began operating a U.S. Climate Reference Network (USCRN) site on the White Clay Creek watershed, just west of the Stroud Center.  The goal of the USCRN is to monitor climate change far into the future using state-of-the-art instrumentation within a stable, centrally-run network of monitoring stations.

The primary variables monitored are precipitation and temperature with secondary variables of wind speed, solar radiation, and infrared (ground) temperature. Initial equipment and installation costs were funded through a generous grant from the Davenport Foundation with site maintenance and upkeep covered by the USCRN program.

USCRN is operated on a real-time basis.  This is a benefit not just to the Stroud Center’s scientists but to all of our neighbors in southeastern Pennsylvania.  The Stroud USCRN real-time data page provides data for the previous 12 hours along with daily and monthly summaries.
