공기질 측정기 위젯은 지정된 위치의 공기질을 표시하는 맞춤설정 가능한 HTML 요소를 제공합니다. 이를 사용하면 최소한의 코드로 Air Quality API에서 현재 공기질 정보를 앱 또는 웹페이지로 가져올 수 있습니다.
공기질 측정기 위젯은 선택한 위치에서 사용할 수 있는 경우 로컬 AQI를 반환하는 CurrentConditions.Lookup 메서드를 사용합니다. 공기질 측정기 위젯은 미국 EPA 현지 AQI를 지원하며 향후 추가 현지 색인을 지원할 계획입니다. 공기질 측정기에서 아직 현지 AQI를 지원하지 않는 경우 범용 AQI가 표시됩니다. 자세한 내용과 기본 CurrentConditions.Lookup 메서드의 최신 적용 범위 세부정보는 AQ 지수 및 공기질 API 지원 국가 및 사용 가능한 AQI를 참고하세요.
다음 예는 지도에 삽입된 공기질 측정기 위젯을 보여줍니다. 지도를 클릭하여 특정 위치의 공기질을 표시합니다.

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.
