How do wireless meat thermometers work?
There are a variety of ways wireless thermometers work. This simplest is a wired probe connected to a base that shows the current temperature. Complexity increases with Bluetooth probes, but the same process follows. The base communicates with a remote or app, and that piece is where the wireless designation comes into play. Some of these models are strictly Bluetooth; others use RF technology, and others bridge from Bluetooth to WiFi for multiple connection points.
