May 10, 2019 · I built a working sensor using the arduino starter kit photoresistor (datasheet) using a 10kOhm resistor and a 5V source but want to understand it better. Edit: afer helpful comments, this …

I mean, photoresistor is already a resistor, why do we have to decrease the voltage in the circuit with an additional resistor? Thanks in advance for your answers.

Sep 30, 2017 · Light dependent resistors (LDRs) today are not that complicated. Designed originally to help count "bottles and/or cans" passing by a moving flow at production factories, they soon lost …

Mar 31, 2016 · simulate this circuit – Schematic created using CircuitLab I have a photoresistor, R1, and as a voltage divider a fixed resistance, R2. There is a voltage of 5V over these two, and the …

Jul 12, 2021 · Why do most of dark sensor circuits in the Internet look like this? It seems to me that in such circuit, photoresistor doesn't limit base current and it doesn't work. I think that photoresistor sh...

Nov 8, 2020 · 5 As an addition to the other answers, typical CdS photoresistors have their maximum sensitivy at green light and nearly none for red and infrared. Also, their sensitive area is very uneven …

May 16, 2017 · I am teaching myself electronics. I designed this circuit to use a photoresistor to trigger a transistor when I hit the photoresistor with a laser pointer. On the Arduino side, I want it to look li...

Nov 1, 2024 · 0 I've recently been trying to do an experiment requiring me to measure light intensity. I didn't have the necessary equipment, but I did have a photoresistor and a Raspberry Pi Pico, so I …
