The Right Tool for the Job: Active and Passive Infrared Sensors

Infrared sensors are more common than most people realize. Learn about the differences between active and passive infrared sensors and their applications.

How Touch Sensors Work

Touch sensors are now standard in most wearables and IoT products. They are used in a wide range of display applications, from smart homes and appliances to security and industrial solutions. There are two common types of touch sensors: capacitive touch sensors and resistive touch sensors. Here’s how they work.

How Do Motion Sensors Work? Types & Applications

Many of the most popular new IoT applications in smart homes and smart industries incorporate motion sensors. From security systems to lighting and more, motion sensors are a simple and effective way to save energy while gathering useful data. The most frequently used motion sensors are Passive Infrared (PIR), Microwave, and Dual Tech/Hybrid. Here’s how they work.

What is a Reed Switch and How Does it Work?

If you visit a modern factory and observe the amazing electronics at work in an assembly cell, you’ll see a variety of sensors on display. Most of these sensors have separate wires for positive voltage supply, ground and signal. Applying power allows a sensor to do its job, whether that’s observing the presence of ferromagnetic metals nearby or sending a light beam out as part of the facility’s security system. The humble mechanical switches that trigger these sensors, like the reed switch, only need two wires to do their jobs. These switches activate using magnetic fields.

How Fingerprint Scanners Work: Optical & Capacitive Scanners

Many modern IoT applications rely on fingerprint sensors for added safety and security, and to easily identify users. Fingerprint sensors are widespread in smartphones and other wearables, as well as in smart industry and smart home applications for entry identification and data security. The two most common fingerprint sensors in use today are optical sensors and capacitive sensors. Here’s how they work.

Top 5 Sensor Development Boards

Sensor development boards provide the ideal platform for developing projects and designs that measure or detect pressure, temperature, humidity, motion, color, and even physical position. These sensor boards offer all the necessary support circuitry that allows you to fully utilize the sensor for evaluation and demonstration. We reviewed our wide range of sensor development boards are selected five that are sure to spark some inspiration or meet the needs of your next application.

What is IMU? Inertial Measurement Unit Working & Applications

The term IMU stands for “Inertial Measurement Unit,” and we use it to describe a collection of measurement tools. When installed in a device, these tools can capture data about the device’s movement. IMUs contain sensors such as accelerometers, gyroscopes, and magnetometers.

Image Sensor Module, Vision Module, Camera Module - What Are the Differences?

A number of modules for capturing images are available for image processing applications with embedded vision. They have different names, such as image sensor module, camera module or vision module. What are the differences between these modules?

Top Arduino Compatible Sensors: Types of Arduino Sensors Compared

Arduino has become popular in tinkering communities and maker movements for being a user-friendly way to implement complex electronics hardware easily into DIY projects. However, many of the accessories that have found their way into the Arduino ecosystem are backed by very professional-grade, production-ready electronics components, making Arduino an increasingly valuable toolset in the engineering and design community. This article will cover some of the top Arduino-compatible sensor tools that feature popular sensing technologies commonly found in the electronics industry and will cover the basics of each technology.
