long-distance relationship: a relationship, typically a romantic one, in which the two people live far enough apart that they cannot see each other often: My boyfriend and I had an LDR for two years.

What is LDR used for?

Photoresistors, also known as light dependent resistors (LDR), are light sensitive devices most often used to indicate the presence or absence of light, or to measure the light intensity.

Is LDR a diode?

(A photo diode and a photocell (LDR) are not the same, a photo-diode is a pn junction semiconductor device that converts light to electricity, whereas a photocell is a passive device, there is no pn junction in this nor it “converts” light to electricity).

How does an LDR sensor work?

The working principle of an LDR is photoconductivity, which is nothing but an optical phenomenon. When the light is absorbed by the material then the conductivity of the material enhances. When the light falls on the LDR, then the electrons in the valence band of the material are eager to the conduction band.

What is a LDR girlfriend?

A long-distance relationship (LDR) or long-distance romantic relationship (LDRR) is an intimate relationship between partners who are geographically separated from one another. Partners in LDRs face geographic separation and lack of face-to-face contact.

Can you fall in love LDR?

Long-distance relationships have garnered quite the bad rep for being pretty much impossible, but most of us at least know a friend of a friend whose cousin was in a long-distance relationship that actually ended up working out. Can a man fall in love long-distance? It is possible! It's just rare.

What is LDR example?

The most obvious application for an LDR is to automatically turn on a light at a certain light level. An example of this could be a street light or a garden light.

Is LDR a sensor?

In order to detect the intensity of light or darkness, we use a sensor called an LDR (light dependent resistor).

Is LDR passive or active?

Every component in the audio signal chain imparts its own coloration to the sound; passive preamps much less so than active preamps. LDR passive preamps are THE most neutral sounding preamp available and are essentially without coloration.

What type of resistor is LDR?

A photoresistor (also known as a Photocell, or light-dependent resistor, LDR, or photo-conductive cell) is a passive component that decreases resistance with respect to receiving luminosity (light) on the component's sensitive surface.

What kind of sensor is LDR?

What kind of sensor is the LDR Sensor? Explanation: The LDR sensor is a passive sensor since it requires no external supply of voltage in order for it to work. It simply acts as a variable resistor and changes the resistance of itself while light of varying intensity falls on it.

What are the two types of LDR?

According to the spectral characteristics of LDRs, there are three types of LDRs: - Ultraviolet LDR: more active to ultraviolet light, including cadmium sulfide, cadmium selenide LDR, etc., used for UV exploration. - Infrared LDR: Lead sulfide, lead telluride and lead selenide are the main ones.

What is LDR made of?

As its name implies, the Light Dependent Resistor (LDR) is made from a piece of exposed semiconductor material such as cadmium sulphide that changes its electrical resistance from several thousand Ohms in the dark to only a few hundred Ohms when light falls upon it by creating hole-electron pairs in the material.

How is LDR used in street light?

LDR sensor is used for detecting the presence of surrounding light so that during the day time when sun is bright, the street light is switched off automatically. During the night time when there is no light, the LDR sends signal to microcontroller to turn on the street light.

How do you measure a LDR?

The LDR sensor illuminated with a light source will obtain a resistance value that can be measured using a multimeter (ohm meter) and the value of the intensity of light produced will be measured in an Arduino-based lux meter.

How long do LDR usually last?

Forty percent of all long-distance relationships end in breakups, and on average those relationships last just four and a half months.

Does LDR lead to cheating?

There will be adjustments, and yes, the risk of cheating in a long-distance relationship will always be there. But if you and your partner would work together and have open communication, then there's a greater chance that you will overcome this challenge. Remember, love is strong when two people work together.

How do you flirt with your LDR?

Try messages like:

"Suddenly, all the love songs are about you."
"You're the only guy for me in the whole wide world."
"I see your face every time I close my eyes."
"Happiness is having someone to think about. I'm very happy."
"You are my favorite daydream."

How do I know my LDR loves me?

15 signs of true love in a long-distance relationship

Strong commitment.
They will be patient with you. ...
You trust each other. ...
Their close circle know about you. ...
You discuss future goals. ...
You can talk to them about anything. ...
They respect you. ...
You don't hold onto grudges.

How often do LDR couples meet?

According to Dr. Guldner at The Center for the Study of Long-distance Relationships, the average couple visits each other 1.5 times a month. In some cases, partners have to go months without seeing each other.
