This type of sensor is often seen in\r\nautomatic towel and soap dispensers or automatic faucets. With the ability to\r\ndetect objects qualitatively up to 20cm away, you will be able to detect if\r\nsomething is there and if it is closer or further away since the last reading.\r\nUtilizing our handy Qwiic system, no soldering is required to connect it to\r\nthe rest of your system. However, we still have broken out 0.1\"-spaced pins in\r\ncase you prefer to use a breadboard. The SparkFun Proximity Sensor Breakout is\r\na great digital alternative to the popular analog based Sharp sensors. The\r\nVCNL4040 has no dead zone and can read all the way up to the face of the\r\nsensor. This sensor also has an ambient light sensor built it which is\r\nexcellent if you need a digital light sensor for your next glitter cannon. If\r\nyou need quantitative distance readings (for example sensing that an object is\r\n177mm away) check out the SparkFun 2 meter and 4 meter Time of Flight (ToF)\r\nsensors with mm accuracy. Note: The I2C address of the VCNL4040 is 0x60 and is\r\nhardware defined. A multiplexer\/Mux is required to communicate to multiple\r\nVCNL4040 sensors on a single bus. If you need to use more than one VCNL4040\r\nsensor consider using the Qwiic Mux Breakout.\u003c\/p\u003e \r\n\r\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\r\n \u003cul class=\"a\"\u003e\r\n \u003cli\u003eThe SparkFun Proximity Sensor Breakout is a simple IR presence and ambient light sensor utilizing the VCNL4040.\u003c\/li\u003e\r\n \u003cli\u003eThis type of sensor is often seen in automatic towel and soap dispensers or automatic faucets.
