All of the following devices are connected to the Internet of Things EXCEPT _______________.

An AM/FM radio without any bluetooth or Internet connection capabilities

A digital baby monitor that allows you to stream video and audio of your nursery from the Internet

A smart thermostat that allows you to remotely control your home’s temperature through a mobile app

A wearable device that measures your physical activity and allows you to track your activity through a mobile app

An AM/FM radio without any bluetooth or Internet connection capabilities.

The device that is NOT connected to the Internet of Things is an AM/FM radio without any Bluetooth or Internet connection capabilities.

To determine which device is NOT connected to the Internet of Things (IoT), we need to understand what the IoT is. The IoT refers to the network of physical objects or devices that are connected to the internet and can interact with each other and their environment.

Let's analyze each device to see if it fits the criteria of being connected to the IoT:

1. An AM/FM radio without any Bluetooth or internet connection capabilities: This device does not have the ability to connect to the internet or interact with other devices. Therefore, it is NOT connected to the IoT.

2. A digital baby monitor that allows you to stream video and audio of your nursery from the internet: This device has internet connectivity and allows you to remotely view and monitor your baby's nursery. It qualifies as an IoT device because it can communicate with other devices (such as your smartphone) over the internet.

3. A smart thermostat that allows you to remotely control your home's temperature through a mobile app: This device has internet connectivity and allows you to control your home's temperature remotely, interacting with other devices (e.g., your smartphone). It also qualifies as an IoT device.

4. A wearable device that measures your physical activity and allows you to track it through a mobile app: This device connects to your mobile app over the internet, allowing you to track your physical activity. It also qualifies as an IoT device.

Based on this analysis, the device that is NOT connected to the IoT is the AM/FM radio without any Bluetooth or internet connection capabilities.
