At the same time, with the use of separate gas sensors and MCU solutions, CCS811 can save equipment inventory costs as well as up to 60% of the total area of the board.  \u003cbr\u003e HDC1080 low power consumption, high precision digital humidity sensor with temperature sensor  \u003cbr\u003e DC1080 is a digital temperature sensor with integrated temperature sensor, which can provide excellent measurement accuracy with ultra-low power consumption. HDC1080 supports a wide range of operating power supply voltage, and compared to competitive solutions, the device can provide a wide range of common applications with low cost and low power consumption advantages. Humidity and temperature sensors are factory calibrated.  \u003cbr\u003e The relative humidity is 2% (typical)  \u003cbr\u003e Temperature accuracy of + 0.2 C (typical)  \u003cbr\u003e Excellent stability under high humidity  \u003cbr\u003e 14 bit resolution  \u003cbr\u003e Sleep mode current is 100nA  \u003cbr\u003e BMP280 is an absolute pressure sensor designed specifically for mobile applications. The sensor module is housed in a very compact package. Its small size and low power consumption allow the implementation of such devices in battery powered mobile phones, GPS modules or watches.  \u003cbr\u003e BMP280 is based on BOSCH's proven piezoresistive pressure sensor technology with high accuracy, linearity and long-term stability and robustness of electromagnetic compatibility. Many device operating options offer the highest flexibility, optimized power dissipation, resolution and filter performance. A test example is used in the case that the default setting is for developers in order to make the design as simple as possible.  \u003cbr\u003e application  \u003cbr\u003e GPS enhanced navigation (e.g. time pre improvement, dead reckoning, slope detection)  \u003cbr\u003e Indoor navigation (ground detection, elevator detection)  \u003cbr\u003e Outdoor navigation, leisure and sports applications  \u003cbr\u003e Weather forecast  \u003cbr\u003e Application of health care (e.g. spirometry)  \u003cbr\u003e Vertical speed indicator (e.g. rising or sinking speed)  \u003cbr\u003e Infos:   \u003cbr\u003e   \u003cbr\u003e   \u003cstrong\u003ePackage included:\u003c\/strong\u003e  \u003cbr\u003e ?  \u003cbr\u003e 1 x CJMCU-8128 CCS811+SI7021+BMP280?Carbon Dioxide?CO2 VOCs Temperature Humidity Gas Pressure Sensor  \u003cbr\u003e   \u003cbr\u003e       \u003cimg src=\"https:\/\/img.banggood.com\/images\/oaupload\/banggood\/images\/BA\/E8\/200addc3-b751-48a8-839b-cd0299c7604c.JPG\"\u003e   \u003cbr\u003e    \u003cbr\u003e         \u003cimg src=\"https:\/\/img.banggood.com\/images\/oaupload\/banggood\/images\/17\/B1\/fd5bee00-9144-4729-a9ce-a4fa76b434ad.JPG\"\u003e    \u003cbr\u003e     \u003cbr\u003e           \u003cimg src=\"https:\/\/img.banggood.com\/images\/oaupload\/banggood\/images\/0A\/7C\/4e4e5a34-2c77-4154-84a0-b1ba2c49d6c4.JPG\"\u003e     \u003cbr\u003e      \u003cbr\u003e             \u003cimg src=\"https:\/\/img.banggood.com\/images\/oaupload\/banggood\/images\/22\/08\/1318844e-88ef-4e18-a3f0-c177dbafcf80.JPG\"\u003e      \u003cbr\u003e       \u003cbr\u003e               \u003cimg src=\"https:\/\/img.banggood.com\/images\/oaupload\/banggood\/images\/95\/88\/996a576d-a0b2-40e4-ba34-334116d7c080.JPG\"\u003e       \u003cbr\u003e        \u003cbr\u003e                 \u003cimg src=\"https:\/\/img.banggood.com\/images\/oaupload\/banggood\/images\/DB\/56\/247f8f3a-9ecb-4437-9c29-6c7689dfe89b.JPG\"\u003e                                   \u003cbr\u003e","brand":"ZHIQIAN","offers":[{"title":"Default Title","offer_id":43932635234499,"sku":"ZHIQIAN-023108","price":914.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0661\/4355\/1683\/files\/4e4e5a34-2c77-4154-84a0-b1ba2c49d6c4.jpg?v=1725861670","url":"https:\/\/wrsss.com\/products\/cjmcu-8128-ccs811-si7021-bmp280-carbon-dioxide-co2-vocs-temperature-humidity-gas-pressure-sensor","provider":"Wrsss","version":"1.0","type":"link"}
