问：类似下面的参考电路，光敏传感器光敏电阻的光照阈值怎么确定？答： TR1由R1的电压来控制导通或截止，TR1的导通电压是0.7V，光敏的光电流典型值是6微安@10lux（鑫永诚光源下，不同光源下的光电流会有所差异），把R1设置为100KΩ，则在10lux时Vr1为0.6V，小于0.7V，此时TR1为截止状态 ……

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&

客户问：这款产品用的这款贴片光敏，像这样周围有光照的情况下，光敏因为藏的比较靠里，导致光敏检测到的光照度很小，也会触发线路工作，有没有好的替换建议？建议：用直插光敏，光感头更靠近表面，感光会均匀一些。
