Adafruit VCNL4040 Proximity and Lux Sensor features a proximity sensor that works from 0mm to 200mm and a light sensor ranging from 0.0125lux to 6553lux. This sensor is placed on a breakout board with support circuitry that allows the board to be used with 5V (Arduino/ Metro328) or 3.3V (Feather/Raspberry Pi) logic levels. The VCNL4040 proximity and lux sensor use an I2C interface to seamlessly connect it up with two wires (plus power and ground). This sensor includes the SparkFun qwiic compatible STEMMA QT connectors for the I2C bus.
The VCNL4040 proximity and lux sensor are capable of adjusting the integration time to set the sensitivity of measurements depending on the lighting conditions. This sensor collects measurements for a short period of time and with an integration time of 80ms, each measurement bit of light represents a larger amount of light. If the integration time is increased, then the sensitivity and resolution within the measurement range also increase.
The VCNL4040 proximity and lux sensor are also capable of changing the current and duty cycle of the IR LED that powers the proximity detection to adjust how sensitive proximity measurements are.

Package Includes:

 1 x Adafruit VCNL4040 Proximity and Lux Sensor - STEMMA QT/Qwiic
