상품 특징

• Working Principle: Light passes through an infrared cutoff filter to reduce interference from non-visible light. An internal photodiode converts the light signal into an electric current. After amplification, the current is converted into a digital signal by a 16-bit ADC, and finally the light intensity is calculated using a formula
• High Precision: These sensors has a 16-bit dynamic range, measurement range is from 0 lx to 120 klx, with a resolution of up to 0.0036 lx/ct. It can adapt to a variety of lighting environments from extremely dark to extremely bright, and accurately detect tiny lighting changes
• Digital Interface: Communicates via a standard I2C interface, making it easy to connect to a microcontroller. Onboard 3.3V regulator and logic level converter allow you to use it with either 3.3V or 5V power/logic microcontrollers
• Low Power Consumption: As low as 2μA in active mode and only 0.5μA in shutdown mode, suitable for battery-powered devices and IoT applications
• Application Scenarios: Automatically adjust screen backlight brightness to improve user experience; automatically adjust the brightness of display devices; automatically control lighting equipment according to ambient light intensity to achieve energy-saving and comfortable lighting environment
