摘要: A light measuring device includes one or more photodiodes, which generate current in relation to the received light, and at least capacitor for integrating generated current. The amount of charge stored completion integration is roughly detected by number capacitors used and/or voltage across capacitor. source capable producing different levels accordance with provided changing time needed change measured so as obtain value total thus intensity.
