Andurisõlmed

Andurisõlmed, commonly referred to as sensor nodes, are fundamental components in many distributed sensing systems. These small, self-contained devices are equipped with one or more sensors, a processing unit, a communication module, and a power source. Their primary function is to collect data from their immediate environment, process it, and then transmit it to a central location or other nodes within a network.

The sensors incorporated into andurisõlmed can vary widely depending on the application. They might measure physical parameters such as temperature, humidity, light, pressure, or motion. More sophisticated nodes can also detect chemical compounds, acoustic signals, or even biological markers. The processing unit, often a low-power microcontroller, handles tasks like data aggregation, filtering, and basic analysis. The communication module enables wireless or wired transmission of the collected data, utilizing technologies like Wi-Fi, Bluetooth, Zigbee, or cellular networks.

Andurisõlmed are typically deployed in large numbers to form a sensor network. This distributed nature allows for wide-area monitoring, redundancy, and the collection of detailed spatial and temporal data. Applications range from environmental monitoring, smart agriculture, and industrial automation to healthcare, urban planning, and military surveillance. The design and deployment of andurisõlmed often involve considerations for energy efficiency, network scalability, and data security due to their often remote or unattended operation. Their modularity and decreasing cost have made them increasingly prevalent in the Internet of Things (IoT) ecosystem.
