Adafruit VCNL4200 Long Distance IR Proximity and Light Sensor - I2C Interface, STEMMA QT
The Adafruit VCNL4200 is a dual-function I2C sensor module integrating long-range IR proximity detection (up to 1.5m) and a high-dynamic-range ambient light sensor (0.003-1570 lux). It is STEMMA QT compatible for plug-and-play connectivity with Raspberry Pi, Arduino, and other 3.3V/5V microcontroller platforms.
Features
- Dual-function sensor combining long-range IR proximity (up to 1.5m) and ambient light sensing (0.003-1570 lux).
- I2C digital interface with STEMMA QT connectors for solderless prototyping and system integration.
- Intelligent background light cancellation and red glow immunity for stable proximity readings.
- Fully configurable sensitivity via adjustable IR LED power, duty cycle, and integration time.
- Programmable interrupt outputs for both proximity and light sensing thresholds.
