Distance Proximity Lux VCNL4040 Sensor - STEMMA QT / Qwiic Adafruit

Distance Proximity Lux VCNL4040 Sensor - STEMMA QT / Qwiic Adafruit

The VCNL4040 is a versatile two-in-one sensor from Vishay, combining a proximity sensor and an ambient light sensor on a single chip. It can detect objects from 0 to 200 mm (about 7.5 inches) and measure light levels from 0.0125 lux up to 6553 lux. This breakout board makes it easy to integrate the VCNL4040 into your projects with 3.3V (Feather/Raspberry Pi) or 5V (Arduino/Metro328) logic levels.
