Hello Hackers! Today we have a really interesting topic. Searching the internet, I didn't find any simple solution on "How to read data from car parking sensors," so I decided to write a short and ...

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 ...

Abstract: Magnetic field sensor devices have been widely used to track changes in magnetic flux concentration, and the Hall sensors are promising in many engineering applications. Design optimization ...

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 ...

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 ...

A Hall-effect sensor is a transducer that converts a magnetic field directly into a usable electrical voltage. It enables engineers to perform non-contact measurement of shaft rotation, detect the ...

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 ...
