Exposure Notification, an API built by Google and Apple, is only a software intermediary within a device and it cannot act as a sensor by itself.
It works on Bluetooth that will allow a participating app to function once it becomes available and installed. It is a base framework provided by Google and Apple and is useless without an app. It allows users to take part in digital contact tracing and help minimize the spread of the infectious disease. We can choose not to use exposure notifications and opt-out voluntarily. Also, the current system cannot be misused as it does nothing without one's permission, and no one can install an app to the device remotely.
