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 time, you're in luck! The VCNL4200 can do that , 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. To make life easier so you can focus on 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 (/) or 5V (/Metro328) logic levels. **Note that while the chip itself is spec'd for 1.5-meter distance measurements, that depends a bit on optimal lighting situations and high-power configuration.** We've found that 50-100 cm is a good range to expect, and you 't get a lot of accuracy/ as the detection object gets farther away. Additionally, since it speaks you can easily connect it up with two wires (plus power and ground!). We've even included Qwiic-compatible STEMMA QT connectors for the bus so you don't even need to solder!, Weight: 0.0220462262 pounds, Manufacturer: Teuypty
