The two methods end up in contention/conflict with each other. The motion sensor and photocell units need 24x7 power. They do not work on reduced power, partial power or the wacky waveform you get out of a triac dimmer, which is made only for lights.
WebJul 18, 2024 · An LDR or light dependent resistor is also known as photo resistor, photocell, photoconductor. It is a one type of resistor whose resistance varies depending on the amount of light falling on its surface. When the light falls on the resistor, then the resistance changes. These resistors are often used in many circuits where it is required to ...
The photons need a minimum threshold frequency (a minimum amount of energy) to free electrons and produce a photoelectric effect, known as the work function. In the example shown here, the violet photons have enough energy to knock out electrons, but the red photons don't. See more Photo: A typical light-dependent resistor (LDR).
