Sensors Technical Articles

Hall-effect-based ICs such as the A1337 can help your device to perform a variety of sensor tasks related to angular motion.

Despite the convenience of CMOS imagers, CCD imagers still have their place. And if you really need low-light performance, consider a device with EMCCD technology, such as the KAE-02152....

Transmit humidity and temperature data with a fully functional, off-the-shelf, battery-less wireless sensor node.

Researchers develop a wearable sensor for detecting important analytes in sweat for monitoring dehydration.

The grid-EYE click provides a user-friendly introduction to advanced thermal sensing and detection.

You can do a lot with ultrasound, and whatever you’re doing will be easier with a highly integrated IC such as the PGA460-Q1.

In this article, we'll first study types of noise and then try to eliminate them by filtering the data. Finally, we'll try to find peaks in that data....

The AS7261 is a highly integrated sensor that provides optical measurements via a digital interface.

Quaternions are mathematical operators that are used to rotate and stretch vectors. This article provides an overview to aid in understanding the need for quaternions....

This article discusses the ideas involved in measuring and interpreting the current-voltage curves of solar cells, batteries, and unknown materials....

Tutorial on designing a Bluetooth Low Energy (BLE) circuit with the ability to measure 9-axis motion, humidity, and temperature.

Embedded and wearable systems require new ideas for input controller hardware. But older software still expects a keyboard and mouse. How do we bridge the gap without having to write kernel...

In part one of this instrumentation and control (I & C) series, we'll go over the fundamental terminology and concepts used when working with industrial plants....

Learn the basics of what LiDAR is, how it works, and how it's applied.

Sensor fusion is the art of combining multiple physical sensors to produce accurate "ground truth", even though each sensor might be unreliable on its own....

In this article, we will learn how to analyze circuits that utilize forward conducting diodes. We will also talk about the exponential model, constant voltage drop model, as well as the ideal...

This article presents some basic cap-sense circuit configurations and discusses how to deal with low- and high-frequency noise.

In this article, we will take a detailed (but not too detailed) look at the electrical principles that allow us to detect the presence of a human finger using little more than a capacitor....

In this article, we will look at the characteristics of junction diodes and learn how to analyze circuits containing diodes that operate in the forward, reverse, and breakdown biases....
