While searching for new products on AliExpress, I came across the SayoDevice OSU O3C, which looks very similar to other macro ...

Allegro MicroSystems is introducing the ACS37017, a Hall effect current sensor targeting power converters, EVs, industrial motor control and clean energy systems. The device integrates a stable, ...

Abstract: This paper presents a CMOS-compatible triaxial Hall sensor featuring a novel vertical Hall device (VHD) structure that achieves high sensitivity and low cross-axis interference. The proposed ...

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 ...

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 ...

If you read about Hall effect sensors — the usual way to detect and measure magnetic fields these days — it sounds deceptively simple. There’s a metal plate with current flowing across it in one ...

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 ...

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 ...
