Abstract
An electronic device may have an ambient light sensor for gathering ambient light measurements. The ambient light sensor may include multiple channels for measuring different wavelengths of ambient light. An additional, modified, channel may be formed in the ambient light sensor to measure radio-frequency signals that may interfere with the ambient light measurements due to electromagnetic interference. Alternatively, circuitry separate from the ambient light sensor, such as an antenna, may measure the radio-frequency signals. If the radio-frequency signals exceed a threshold, the ambient light sensor measurements taken in the presence of the radio-frequency signals may be discarded or corrected. If the radio-frequency signals do not exceed a threshold, the ambient light sensor measurements may be kept. Therefore, the ambient light measurements that are kept and relied upon by the electronic device may be free from electromagnetic interference.
