How to use the Sensors panel to test device geolocation and orientation?

The Sensors panel in developer tools is designed to simulate the physical environment of a mobile device, such as GPS coordinates, spatial orientation, and battery charge level. To open it, press the shortcut to invoke the command line in the developer panel, type the word Sensors, and press enter. This panel is indispensable when developing and testing web applications that use geolocation, map services, or interactive games that react to screen tilts.

In the geolocation section, you can select one of the predefined world locations, such as London or Tokyo, or enter custom latitude and longitude values. The application will perceive these coordinates as if the device is actually at the specified location. You can also select the option to simulate missing geolocation to check how your code handles errors accessing user location data.

The device orientation section allows you to emulate the rotation of a phone or tablet in space along three axes: alpha, beta, and gamma. This makes it possible to test motion and device orientation event handlers without having to constantly pick up a real smartphone. Additionally, the panel allows you to emulate network connection status and battery charging status, which helps check the power-saving features of your web application.
