The photodiode current is converted to digital values by an integrated ADC. Automatic full-scale ranging adjusts the gain setting to optimize resolution across the wide 1-64k lux range without user intervention. The I2C interface provides read access to the 16-bit lux data and configuration registers.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>VDD<\/td><td>Power supply (1.7-3.6V)<\/td><\/tr><tr><td>2<\/td><td>SCL<\/td><td>I2C serial clock<\/td><\/tr><tr><td>3<\/td><td>SDA<\/td><td>I2C serial data<\/td><\/tr><tr><td>4<\/td><td>GND<\/td><td>Ground<\/td><\/tr><tr><td>5<\/td><td>INT<\/td><td>Interrupt output (optional)<\/td><\/tr><tr><td>6<\/td><td>NC<\/td><td>No connect<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Display backlight control<\/li><li>Mobile device ambient sensing<\/li><li>Smart lighting systems<\/li><li>Industrial light monitoring<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Spec<\/th><th>Package<\/th><\/tr><tr><td>BH1730FVC<\/td><td>Rohm<\/td><td>I2C ambient light sensor<\/td><td>2.0x2.0mm<\/td><\/tr><tr><td>APDS-9301<\/td><td>Broadcom<\/td><td>I2C ambient light sensor<\/td><td>2.0x2.0mm<\/td><\/tr><tr><td>VEML7700<\/td><td>Vishay<\/td><td>I2C ambient light sensor<\/td><td>2.0x2.0mm<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/9797","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/comments?post=9797"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/9797\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=9797"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=9797"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=9797"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=9797"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
