The answer is all of the above.
The characteristics of an IoT sensor node are energy-efficiency, distributed sensing and low-cost.
Internet of Things (IoT) is related to the interconnection of embedded systems using sensors and wireless technology such as Bluetooth, WiFi to mention a few. The technology used depends on how the nodes are connected and how much data has to be collected. Often, the embedded systems used are micro-controller computers that use sensors. These computers are independent of each other.
