WebWith a current mirror. You use a pair of PNP transistors to just mirror the drain current from the sensor, and make the second PNP to just supply a copy of such current to the device receiving it. Sometimes it is awkward to think to use current mirror in the normal PCB with regular components, and yes, it is. WebApr 10, 2024 · When light sensors on the mirror catch glare, a current is sent to the electrochromic gel that sits between two pieces of glass in the mirror. This current causes the gel to change color, which dims the appearance of the mirror. When there is no more glare to trigger the sensor, the current stops.
