Understanding OBD2 WiFi Dongles

An OBD2 WiFi dongle acts as a bridge between your car’s computer and your smart device, transmitting data wirelessly via a WiFi connection. This allows you to monitor various parameters like engine speed, coolant temperature, fuel pressure, and much more.

The dongle plugs into your car’s OBD2 port, typically located under the dashboard on the driver’s side. Once plugged in, it creates a WiFi network that your smartphone or tablet can connect to. You’ll then need a compatible app, many of which are free or available for a small fee. These apps interpret the data transmitted by the dongle and present it in a user-friendly format.
