Smart home automation is the ultimate life hack, in my humble opinion. Whether for efficiency, accessibility, nerding out, or just plain laziness, all you need are smart home devices and a little ...

Part 1 covered ambient light sensor basics and key characteristics. The choice of which ambient light sensor is best for an application is up to the end-user. The digital light sensor approach is ...

An overwhelming majority of handheld devices these days have ambient light sensors built into them. A large percentage of TVs and monitors do, too, and that proportion is growing. The sensors allow ...

Inductive sensors are non-contact proximity sensors that detect ferrous targets, ideally ones made of mild steel thicker than one millimeter. They consist of four major components: a ferrite core with ...

A wearable fitness tracker makes use of special gizmos to keep track of various parameters of the individual wearing the tracker. These sensors measure a number of parameters such as acceleration, ...

Discover a sensor the size of an IC that works by measuring the time it takes light emitted to bounce off of a target and return. About a year ago, a coworker told me about a new kind of distance ...

To enable the development of wearable devices that possess advanced ultraviolet (UV) detection functions, scientists from Nanyang Technological University, Singapore (NTU Singapore) have created a new ...

Robots are developed for a wide variety of uses. These include assembly, welding, monitoring marine life, rescue and recovery and even vacuuming the floor. Because of this, there is a multitude of ...

Autonomous cars often proudly claim to be fitted with a long list of sensors—cameras, ultrasound, radar, lidar, you name it. But if you’ve ever wondered why so many sensors are required, look no ...

Smartphone cameras have improved dramatically since the first camera-equipped cell phone was introduced in 1999, but they are still subject to tiny errors in the alignment of different wavelengths of ...

What are the most common types of light sensors? Two of the most common light sensors are phototransistors and positive-intrinsic-negative (pin) photodiodes. Both generate signals that vary with ...
