Description

technical field [0001] The invention relates to the field of optical technology, in particular to a digital optical sensor and an ambient light monitoring device. Background technique [0002] At present, the detection of optical parameters, such as color temperature, illumination, etc., usually requires professional detectors. These professional detectors are often expensive and bulky. Multiple corresponding detectors may be required to detect multiple optical parameters, and these Professional detectors cannot connect to the Internet of Things and upload data in real time so that no one can monitor in real time. SUMMARY OF THE INVENTION [0003] The invention provides a digital optical sensor and an ambient light monitoring device, which solves the technical problems of high price, large volume and inability to transmit in real time in the traditional optical parameter detector. [0004] A digital optical sensor of the present invention includes: a photosensitive circui...
