Visible Light Sensor LX1970 Measurement of White Light Circuit
As shown for the measurement of white light circuit constituted by the visible brightness sensorLX1970. By the UCC, the current source and the white LED light source emits visible light, visible light and convert the current signal received by the LX1970. SNK side, SRC-side of each series a microampere table, were measured the photocurrent ISNK, ISRC, the readings of the microammeter value reflects the level of brightness.
