The APDS-9301 Ambient Light Sensor Breakout is an I²C-compatible luminosity sensor board that converts light intensity to a digital output signal. This breakout is fairly simple and has been specifically designed with only a few ancillary passive components in addition to the ADPS-9301 IC itself. All readings are returned to your chosen microprocessor in lux, providing precise Illuminance measurement under diverse lighting conditions.

On top of each board breaking out our standard I²C pin-out of SCL, SDA, 3.3V and GND, we’ve also provided an INT pin so the APDS-9301 can be programmed to generate an interrupt under certain conditions. It is important to note that this breakout is non-instantaneous, so it will require some integration time to take a measurement.
