IoT system components
Typical IoT systems consist of 3 main elements
(Figure 15)
, brief described below. In order to set
communication, each element must be properly configured.
1.
Node
– device with sensors and a wireless communication module that gathers data, forms
the payload and sends it to the gateway.
2.
Gateway
– device similar to routers, equipped with a LoRa concentrator, that receives LoRa
packets and send them to the Internet-connected server.
3.
Server
– in most cases, a cloud-based service where data is processed, stored, analysed, and
presented in user-friendly ways (via a user interface); Yosensi default and recommended
tools are Yosensi Management Platform (for IoT structure management) and Grafana (for
data presentation).
