## Definition
**Sensor Networks** denote **distributed arrangements of interconnected sensors** that **collectively measure, communicate, and aggregate environmental or operational data** across space and time. Networks include **ground-based weather stations, soil moisture sensors, air quality monitors, acoustic sensors**, and increasingly **distributed citizen-science networks**. Effective networks provide **spatial coverage, redundancy, and real-time or near-real-time data streams**.
---
## General Context
In sensor technology and distributed systems, sensor networks enable monitoring at scales and resolutions impossible with centralized collection. Network design challenges include power management, data transmission, calibration, and integration with decision systems.
---
## Key Insight
Sensor network value depends on data quality, timeliness, and integration with decision systems. Networks generating voluminous but unused data provide no decision support and waste resources.
