A Sensor Node in a WSN consists of four basic components. Mobile WSNs. have displays that allow the user to easily change the key, but most simple sensors do not have this type of interface and require a provisioning process to modify the key. IoT sensor data is the data collected by devices found in the Internet of Things (IoT). Therefore, they dont work well for applications such as door locks. The signal will be received by another device such as a gateway, computer or smartphone which will then interpret the data according to its programming instructions before displaying it on screen or storing it in a database, or sending it up to the cloud. However, Z-Wave mesh networks can only support a limited number of wireless sensors and is subject to the limitations of mesh networks described earlier. Smart homes, smart buildings, smart cities, smart agriculture and supply chain management are just a few of the areas that will be dramatically impacted by wireless sensor networks.
