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.
