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 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 ...

The MLX90296 contactless linear sensor combines digital flexibility, ultra low power consumption, adaptable polarity modes, and a space-saving form factor. Melexis has announced the MLX90296, a new ...

Designed by Nova Radio Labs in the US, the Novaduino Environmental Sensor Kit is an Arduino-programmable air quality and weather monitoring solution built around the company’s own Novaduino Display ...

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 ...

Diodes’ AH4930Q sensor detects magnetic fields along the X, Y, and Z axes for contactless rotary motion and proximity sensing. As the company’s first automotive-compliant 3D linear Hall effect sensor, ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

Abstract: This system is designed to get vehicle speed information on the highway. Because the speed of a vehicle on the highway is very influential on other road users. Even based on data taken by ...
