Infrared Sensor
makerA device that detects and measures infrared radiation from objects.
expanded
Infrared sensors are used to detect infrared radiation, which is emitted by all objects above absolute zero temperature. These sensors are crucial in various applications such as detecting motion in security systems and measuring temperature in thermal imaging cameras. Their ability to perceive heat and operate in the dark makes them essential in numerous fields, including night vision technologies and industrial automation.
examples
An infrared motion sensor used in a security lighting system can detect the presence of a person up to 12 meters (approximately 39 feet) away.
Commonly used in residential and commercial security systems to automatically trigger alarms or lights when motion is detected.
An infrared thermal imaging camera with a resolution of 320 x 240 pixels and a temperature detection range from -20°C to +350°C (-4°F to +662°F).
Widely used by firefighters to detect fire hotspots or by electricians to identify overheating components in circuits.
