An electronics heat leak infrared (IR) sensor is an electronic device that measures and detects infrared radiation in its surrounding environment. Infrared radiation was accidentally discovered by an astronomer named William Herchel.
While measuring the temperature of each color of light (separated by a prism), he noticed that the temperature just beyond the red light was highest.
IR is invisible to the human eye, as its wavelength is longer than that of visible light (though it is still on the same electromagnetic spectrum). Anything that emits heat (everything that has a temperature above around five degrees Kelvin) gives off infrared radiation.
There are two types of infrared sensors: active and passive. Active infrared sensors both emit and detect infrared radiation. Active IR sensors have two parts: a light emitting diode (LED) and a receiver.
When an object comes close to the sensor, the infrared light from the LED reflects off of the object and is detected by the receiver. Active IR sensors act as proximity sensors, and they are commonly used in obstacle detection systems (such as in robots).
The Global electronics heat leak IR sensor market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
TI Launches New IR Temperature Sensor – Texas Instruments Inc. (TI) is enabling contactless temperature measurement for the first time in portable consumer electronics with the industry’s first single-chip passive infrared (IR) MEMS temperature sensor.
The TMP006 digital temperature sensor provides manufacturers of mobile devices, such as smartphones, tablets, and notebooks, with the ability to accurately measure device case temperature using IR technology.
This advancement over the current approach of approximating case temperature, based on system temperature, will enable system designers to optimize performance while providing a more comfortable user experience. The TMP006 can also be used to measure temperature outside the device, enabling new features and user applications.
