It is useful for light-level monitoring, automatic display-brightness projects and other prototypes that need an ambient-light reading.<\/p>\n<h4>\ud83d\udd27 Specifications stated for this module<\/h4>\n<ul>\n<li>Sensor: BH1750FVI, digital ambient-light sensor<\/li>\n<li>Interface: I\u00b2C<\/li>\n<li>Listed measurement range: 1\u201365,535 lx<\/li>\n<li>Listed high-resolution step: 1 lx<\/li>\n<li>Listed typical current: 0.12 mA<\/li>\n<li>Listed measurement variation: \u00b120%<\/li>\n<li>Peak spectral sensitivity: approximately 560 nm<\/li>\n<li>50\/60 Hz light-noise rejection<\/li>\n<li>Board size: 13.9 \u00d7 18.5 mm<\/li>\n<\/ul>\n<p><strong>Voltage note:<\/strong> the product listing describes the module as suitable for 3\u20135 V systems. The BH1750FVI IC itself is specified for a 2.4\u20133.6 V supply. Breakout boards differ in their regulators and I\u00b2C level shifting, so verify the markings or documentation of the supplied board before applying 5 V or connecting its SDA\/SCL lines to 5 V logic. Use 3.3 V logic unless the board\u2019s compatibility is confirmed.<\/p>\n<h4>\u2699\ufe0f Measurement and I\u00b2C address<\/h4>\n<p>The sensor converts incident light into a 16-bit digital result. Its ADDR input selects one of two I\u00b2C addresses: ADDR low selects <code>0x23<\/code>; ADDR high selects <code>0x5C<\/code>. The address shown in software may appear shifted or formatted differently by some libraries. High-resolution mode has a nominal 1 lx step; readings and conversion time depend on the selected measurement mode.<\/p>\n<h4>\ud83d\udca1 Typical uses<\/h4>\n<ul>\n<li>Ambient-light monitoring<\/li>\n<li>Automatic brightness control for displays<\/li>\n<li>Lighting and home-automation prototypes<\/li>\n<li>Arduino and other microcontroller projects<\/li>\n<\/ul>\n<h4>\ud83d\udccc Module pinout<\/h4>\n<ul>\n<li><strong>VCC:<\/strong> module supply; confirm the voltage supported by the supplied breakout<\/li>\n<li><strong>GND:<\/strong> ground<\/li>\n<li><strong>SDA:<\/strong> I\u00b2C data<\/li>\n<li><strong>SCL:<\/strong> I\u00b2C clock<\/li>\n<li><strong>ADDR:<\/strong> I\u00b2C address selection, if brought out on the board<\/li>\n<\/ul>\n<h4>\ud83d\udd0c Basic Arduino example<\/h4>\n<p>The original source code is preserved below.
