An infrared-dependent resistor (or IR sensor) is a device that changes its resistance based on the intensity of infrared light it detects. These sensors are commonly used in applications like motion detection, proximity sensing, and object detection where the presence of objects can be determined based on infrared radiation. The resistance of the sensor changes based on the amount of infrared light detected, allowing it to be used in various electronic circuits for automation and control purposes.

What does an infrared sensor detect?
An infrared sensor detects infrared radiation emitted by objects based on their temperature. It can detect heat signatures, motion, and proximity by measuring changes in infrared light levels.
What does E1 mean on a infrared heater?
E1 on an infrared heater typically indicates an error related to the temperature sensor. It could mean that the sensor is malfunctioning or that there is an issue with the wiring. Check the sensor and connections to troubleshoot the problem.
In technology what does LDR stand for?
LDR stands for Light Dependent Resistor. It is a type of resistor that changes its resistance based on the amount of light that falls on it. This change in resistance allows LDRs to be used in light-sensitive applications, such as automatic lighting controls.
Who invented the light dependent resistor?
J.B. Gunn is credited with the invention of the light dependent resistor in the early 20th century. It was initially developed for military applications during World War II.
How do you calculate infrared strength?
Infrared strength can be calculated by measuring the intensity of infrared radiation with a spectrometer or infrared sensor. The strength of infrared radiation is influenced by factors such as the temperature of the emitting object and the distance from the source. The data collected from these measurements can be used to quantify the strength of the infrared radiation.
How do you set the sensitivity of a light dependent resistor?
using a variable resistor we can adjust the sensitivity of a light dependent resistor
Is Light dependent resistor an example of resistor?
yes, a variable resistor
What does an infrared sensor detect?

What is an LDR symbol?
An LDR is a Light dependent resistor.
Who invented light dependent resistor?
K. K.
What are the advantages and disadvantages of light dependent resistor?
itroduction on LDR
What is the meaning of LDR?
LDR refers to Light Dependent Resistor.
How do you use resistor in a sentence?
I installed a resistor inline with my oil pressure sensor. The resistor in a circuit will usually disperse energy as heat.
What does E1 mean on a infrared heater?
E1 on an infrared heater typically indicates an error related to the temperature sensor. It could mean that the sensor is malfunctioning or that there is an issue with the wiring. Check the sensor and connections to troubleshoot the problem.
What sensor do you use to detect a moving target crossing a certain point?
Infrared proximity sensor.
