Arduino has just announced the Arduino Matter Discovery Bundle (AKX00081), an all-in-one development kit designed to help ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

Allegro’s ACS37200 200-A Hall current sensor slashes power dissipation with its 50-µΩ shunt, offering 1,400 V of isolation in a compact PSOF package for high-voltage systems. How the ACS37200’s 50-µΩ ...

Abstract: The application of Hall-based BLDC motors ranges from automotive accessory components such as oil and water pumps to high speed compressors. This paper proposes a new twelve-step ...

The Smart SMS Alert System using Seeed Studio Xiao ESP32 is one of the compact IoT projects that uses an HC-SR04 ultrasonic sensor to detect nearby movement. The system acts like a motion detector ...

The technique is called high-side current sensing. However, measurements at that location are fraught with problems. Of primary concern is that the measurement is at main line voltage, a problem if ...

Melexis has brought out a linear Hall-effect sensor that draws less than 5 µA at 100 Hz and integrates digital filters for enhanced performance. Its flexible architecture is available in multiple ...

Need a Hall sensor? A strip of copper, a strong magnet, and an LM358 are all you need to explore the Hall effect hands-on. This experimental setup turns microvolt signals into measurable millivolt ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

Insight on Diodes Inc.’s first automotive-compliant 3D linear Hall-effect sensor. How it allows for reliable and high-precision contactless rotary motion and proximity detection. Application targets ...
