Barometer

Barometer is a handy Chrome extension that displays the current air pressure using your device's built-in air pressure sensor. It provides real-time readings of the current atmospheric pressure along with the recorded maximum and minimum values. To ensure accuracy, users can adjust the sensor calibration manually. Beyond air pressure, Barometer also calculates altitude based on the pressure data, enabling height measurements even without GPS reception. This makes it useful for environments such as caves or indoor spaces where GPS signals are unavailable. Please note that the functionality depends on your device supporting an air pressure sensor.
