Thermometer

The 🌡️ thermometer emoji as a looping Lottie animation from Google's Noto Emoji Animation set.

🌡️ Thermometer is one of the animated emoji in Google's Noto Emoji Animation set — the same thermometer emoji (U+1F321 U+FE0F) drawn as a short looping Lottie animation. Lottie files are vector, so the animation stays sharp at any size and is usually much lighter than a GIF or a video.

🌡️ is the thermometer emoji, part of Unicode's Travel & Places group, added in Emoji 0.7 (2014). Unicode's keyword list links it with “weather”.

Where the animated Thermometer works best

Websites and landing pages — a looping 🌡️ adds motion to a hero, a feature card or an empty state without a video file.
Apps and product UI — success, error and onboarding screens feel less static with a small animated emoji next to the message.
Presentations, videos and social posts — Google also publishes GIF and WebP versions of each animation for tools that cannot play Lottie.

export function Thermometer1f321() {
  const [data, setData] = useState<unknown>(null);
  useEffect(() => {
    fetch("https://fonts.gstatic.com/s/e/notoemoji/latest/1f321_fe0f/lottie.json").then((r) => r.json()).then(setData);
  }, []);
  if (!data) return null;
  return (
    <Lottie
      animationData={data}
      loop
      autoplay
      style={{ width: 160, height: 160 }}
    />
  );
}

Best practices

Respect prefers-reduced-motion: pause the animation and show the plain character 🌡️ for people who turn motion off.
Lazy-load the player below the fold so the animation library does not slow down the first paint.
Keep the original file: Google updates the animations in place, so linking to its copy keeps yours current.
Credit the source wherever you use it, as the CC BY 4.0 licence requires.

Animated emoji FAQ

What does the animated 🌡️ thermometer emoji mean?: 🌡️ is the thermometer emoji, part of Unicode's Travel & Places group, added in Emoji 0.7 (2014). Unicode's keyword list links it with “weather”.
Can I use the animated thermometer emoji commercially?: Yes, with credit. Google publishes Noto Emoji Animation under the Creative Commons Attribution 4.0 licence (CC BY 4.0), which allows personal and commercial use — in apps, websites and videos — as long as you credit Google, for example “Noto Emoji Animation by Google, CC BY 4.0”.
Where does the animation file come from?: From Google's own CDN: https://fonts.gstatic.com/s/e/notoemoji/latest/1f321_fe0f/lottie.json. DBEmoji does not host or change the file; your browser loads it from fonts.gstatic.com when you open this page.
Can I send the animated 🌡️ in WhatsApp, iMessage or Discord?: Not as this animation. Messaging apps send the plain Unicode character 🌡️ and draw it in their own style, and only some apps animate certain emoji themselves. To share this motion, use the GIF or WebP version, or embed the Lottie file in a website or app.
