Stopping a pressure observer

The following example collects 20 samples and then disconnects the pressure observer to disable receiving any more pressure records.

const samples = [];

function pressureChange(records, observer) {
  for (const record of records) {
    samples.push(record.state);
    // We only want 20 samples
    if (samples.length === 20) {
      observer.disconnect();
      return;
    }
  }
}

try {
  const observer = new PressureObserver(callback);
  await observer.observe("cpu", {
    sampleInterval: 1000, // 1000ms
  });
} catch (error) {
  // report error setting up the observer
}
