3.8 Ambient Light Sensor
A OPT3001 is a sensor that measures the intensity of visible light. The light sensor is mounted on the WFI32-IoT 2.0 board for measuring the light intensity.
The WFI32E03PC module connects to the OPT3001 ambient light sensor through I2C1 and uses a GPIO pin for the user-configurable alert function.
