ldr sensor
An LDR (Light Dependent Resistor) sensor in a fire alarm detects changes in light levels, typically caused by the presence of smoke or flames. When a fire occurs, it can produce a significant amount of light, which the LDR senses by decreasing its resistance and triggering an alarm. This allows the fire alarm system to respond quickly to potential fire situations by alerting occupants and emergency services. However, LDR sensors are often used in combination with other types of sensors, such as smoke or heat detectors, for more reliable fire detection.
An LDR is a Light dependent resistor.
An LDR (Light Dependent Resistor) sensor primarily detects changes in light intensity, so it is not designed to directly detect eyeball movement. However, it could potentially be used in a setup to sense changes in light levels due to eye movement if the eye blocks or reflects light in a detectable way. For precise tracking of eyeball movement, more specialized equipment like eye-tracking cameras or infrared sensors would be more effective.
LDR refers to Light Dependent Resistor.
