Ambient light sensor and electronic equipment

The invention provides an ambient light sensor and an electronic device, which can improve the detection precision and detection performance of the ambient light sensor, and further improve the use experience of a user on the electronic device where the ambient light sensor is located. The ambient light sensor comprises a light filtering unit array which comprises a red light filtering unit, a green light filtering unit, a blue light filtering unit, a white light filtering unit and a transparent light filtering unit, the white light filtering unit is used for allowing visible light signals to pass through and blocking infrared light signals, and the transparent light filtering unit is used for allowing the visible light signals and the infrared light signals to pass through; the pixel unit array comprises a plurality of pixel units, the pixel units corresponding to the white light filtering unit and the transparent light filtering unit are used for jointly detecting the semaphore of infrared light signals in
