光電センサーの照度テスト結果がばらつく理由

Why Do Photocell LUX Test Results Often Appear Inconsistent? In numerous outdoor illumination projects, purchasers and engineers report that measured LUX values do not match the specifications listed on photocell datasheets. This every so often creates apprehension that the photocell is faulty or inappropriately attuned. Though, in most cases, the problem is not product failure—it is inconsistency in the photocell testing method. The truth is that LUX is not a fixed, universal parameter. It is a measured result influenced by the specific testing atmosphere, light source, angle, distance, and optical setup. If these variables change, the measured switching point of a photocell can change as well. Understanding why lux measurement inconsistency occurs […]
