Widget Pengukur Kualitas Udara menyediakan elemen HTML yang dapat disesuaikan untuk menampilkan kualitas udara untuk
lokasi tertentu. Anda dapat menggunakannya untuk menampilkan informasi kualitas udara saat ini dari
Air Quality API ke aplikasi atau halaman web dengan kode
minimal.
Widget Pengukur Kualitas Udara menggunakan metode CurrentConditions.Lookup, yang akan menampilkan
AQI lokal jika tersedia untuk lokasi yang dipilih. Widget Pengukur Kualitas Udara mendukung AQI lokal EPA Amerika Serikat, dengan dukungan yang direncanakan untuk indeks lokal tambahan di masa mendatang. Jika AQI lokal belum didukung oleh Pengukur Kualitas Udara, AQI Universal akan ditampilkan. Lihat
AQ Index dan
Negara yang didukung Air Quality API dan AQI yang tersedia
untuk mengetahui informasi selengkapnya dan detail cakupan terbaru dari metode CurrentConditions.Lookup yang mendasarinya.
Contoh berikut menunjukkan Widget Pengukur Kualitas Udara dengan kondisi saat ini untuk Mountain View, CA.
Tambahkan Widget Pengukur Kualitas Udara ke halaman HTML dengan menambahkan elemen gmp-air-quality-meter, yang juga dapat digunakan untuk menetapkan atribut location, yang menetapkan koordinat lintang dan bujur untuk lokasi yang dipilih:
Contoh berikut menunjukkan Widget Pengukur Kualitas Udara yang disematkan dalam peta. Klik peta untuk menampilkan kualitas udara untuk suatu lokasi.

You can use it to bring current air quality information from the\n[Air Quality API](/maps/documentation/air-quality) to your app or web page with minimal\ncode.\n\nThe Air Quality Meter Widget uses the [`CurrentConditions.Lookup`](/maps/documentation/air-quality/reference/rest/v1/currentConditions/lookup) method, which will return the\nlocal AQI if it's available for the selected location. The Air Quality Meter Widget supports the US EPA local AQI, with planned support for additional local indexes in the future. If local AQI is not yet supported by the Air Quality Meter, it will display the Universal AQI. See\n[AQ Index](/maps/documentation/air-quality/laqis) and\n[Air Quality API supported countries and available AQIs](/maps/documentation/air-quality/coverage)\nfor more information and the latest coverage details of the underlying `CurrentConditions.Lookup` method.\n\nThe following example shows the Air Quality Meter Widget with current conditions for Mountain View, CA.\n\nHow to use the Air Quality Meter Widget\n\nBefore using the Air Quality Meter Widget, [enable the Air Quality API](/maps/documentation/air-quality/cloud-setup#enabling-apis).\n\nAdd the Air Quality Meter Widget to an HTML page by adding the `gmp-air-quality-meter`\nelement, which may also be used to set the `location`\nattribute, which sets the latitude and longitude coordinates for the chosen location: \n\n```html\n\u003cgmp-air-quality-meter location=\"47.656905,-122.407355\"\u003e\u003c/gmp-air-quality-meter\u003e\n```\n\nYou can also set up the Air Quality Meter Widget in JavaScript: \n\n```html\n\u003cscript\u003e\nconst {AirQualityMeterElement} = await google.maps.importLibrary('airQuality');\nconst meterElement = new AirQualityMeterElement({\n location: {lat: 47.656905, lng: -122.407355}\n});\ndocument.body.append(meterElement);\n\u003c/script\u003e\n```\n\nThe following example shows the Air Quality Meter Widget embedded in a map. Click the\nmap to show the air quality for a location.\n\nSee the complete code example \n\nJavaScript \n\n```javascript\nlet map, meter, marker;\n\n// Initialize the map.\nasync function initMap() {\n // Set to the center of the continental US.\n const center = {\n lat: 40.6048080,\n lng: -99.386252,\n };\n\n // Import needed libraries.\n await Promise.all([\n google.maps.importLibrary('airQuality'),\n google.maps.importLibrary('maps'),\n google.maps.importLibrary('marker'),\n ]);\n\n map = document.getElementById('map_element');\n map.innerMap.setOptions({\n mapTypeControl: false,\n fullscreenControl: false,\n clickableIcons: false,\n });\n\n meter = document.getElementById('meter_element');\n marker = document.getElementById('marker_element');\n\n map.center = center;\n marker.position = meter.location = {lat: 37.424100, lng: -122.092692};\n\n // Add an event listener to handle map clicks.\n map.innerMap.addListener('click', async (event) =\u003e {\n marker.position = meter.location = event.latLng;\n });\n}\n\ninitMap();\n\n \n```\n\nCSS \n\n```css\n/**\n * @license\n * Copyright 2019 Google LLC.
