VCNL4200 Long Distance IR Proximity and Light Sensor Module - STEMMA QT Connectors Description

VCNL4200 Long Distance Proximity Sensor excellent for robotic or motion-detection situations. And, if perchance you also needed to measure the amount of light at the same , you're in luck! The VCNL4200 can do that too, with its built-in ambient light sensor (ALS).
The VCNL4200 is a powerful two-in-one sensor, with a proximity sensor that works from 0 to 1.5m (59 inches) and a light sensor with a range of 0.003 to 1570 lux.
**Note that while the chip itself is spec'd for 1.5-meter distance measurements, that depends a bit optimal lighting situations and high-power configuration.** We've found that 50-100 cm is a good range to expect, and you won't get a lot of accuracy/precision as the detection object gets farther away.
To make life easier so you can focus your important work, we've taken the VCNL4200 and put it onto a breakout PCB along with support circuitry to let you use this little wonder with 3.3V (Feather/Raspberry Pi) or 5V (/Metro328) logic levels.
Additionally, since it speaks I2C you can easily connect it with two wires ( power and ground!). We've even included SparkFun Qwiic-compatible STEMMA QT connectors for the I2C bus so you don't even need to solder!

To give you some ability to tune your measurements for your situation, the VCNL4200 lets you adjust the integration for both light sensing and proximity, IR LED power, duty cycle, multi-pulse, and sunlight immunity. There's also interrupt output support for light or proximity measurement thresholds.
