問：類似下面的參考電路，光敏傳感器光敏電阻的光照閾值怎么確定？答： TR1由R1的電壓來控制導通或截止，TR1的導通電壓是0.7V，光敏的光電流典型值是6微安@10lux（鑫永誠光源下，不同光源下的光電流會有所差異），把R1設置為100KΩ，則在10lux時Vr1為0.6V，小于0.7V，此時TR1為截止狀態 ……

Customer A: Hello, this lens does not need to pay attention to the mounting direction when using, spherical NEWOPTO: For the installation method of wall hanging, the two positions are best on the horizontal direction line NEWOPTO:

Customer asked: The resistance of R7, from 10K to 30K, to 100K, In the office light (100lux) will light up, Whether our circuit design is unreasonable, As soon as the power is on, when there's enough light in the office environment, It&

客戶問：這款產品用的這款貼片光敏，像這樣周圍有光照的情況下，光敏因為藏的比較靠里，導致光敏檢測到的光照度很小，也會觸發線路工作，有沒有好的替換建議？建議：用直插光敏，光感頭更靠近表面，感光會均勻一些。
