What’s new in sensors for smart homes: part 3
Air quality sensors have been measuring and monitoring outdoor air quality applications for many years. More recently, they have been used more frequently for indoor applications in smart homes and connect to the home’s Wi-Fi network. One of the more unique sensed items is radon. Similar to other harmful gases, people cannot see or smell […]
How do ear recognition biometrics work?
In the era of face masks, ear recognition can provide a viable alternative to more commonly used facial recognition. The human ear remains relatively unchanged, making it suitable for security authentication applications. It can also be easier to extract information from since it is not subject to variations like facial expressions. Ear recognition biometrics analyze […]
How does voice recognition biometrics work?
A voiceprint, also called a voice template, is a unique pattern of a person’s voice sounds. Based on hundreds of subtle voice characteristics, voiceprints can be used to identify a person, just like fingerprints or facial recognition. The uniqueness of voiceprints derives from the fact that there are over 70 body parts, each of which […]

How do eye & iris scan biometrics work?
Iris scan biometrics is one of two techniques that use unique eyeball characteristics for security and identification purposes. The other technique is retinal scanning. Iris scans are more commonly used because they are quicker and less invasive, but retinal scanning can be more accurate. The two techniques also have different applications. A retinal scan requires […]
Compact TSOT23-3L package Hall switch needs no external components
