The OPT3001 is an ambient light sensor (ALS) with a digital output integrated circuit. It uses a two-wire interface that works with the I2C protocol making it ideal for many applications. The OPT3001EVM is a platform for evaluating the performance of the OPT3001 under various conditions. The OPT3001EVM consists of two PCBs The first is the SM-USB-DIG board that communicates with the computer, provides power and send and receives appropriate digital signals. The second is the OPT3001 test board, which contains the OPT3001 and it’s support circuitry.
