Devices refers to actual physical devices, such as thermostats, fire sensors, smoke sensors, security sensors, water-quality-check sensors, and others. Depending on the type of device, they are split into two different categories:
- IP enabled devices: Devices that can connect over the Internet and can connect directly with a Cloud Gateway, such as Azure IoT Hub.
- Low-powered devices: Small low-powered devices are devices that connect on Bluetooth low energy (Bluetooth LE or BLE), which can't connect directly with a Cloud Gateway. So, for these devices, we will require a component such as device gateway, which connects with these low-powered devices, aggregates and consolidates data from these devices, and then send it across to the ...
