Recently, I’ve been working on a solar off-grid monitoring system. In the system are a few split-core Hall effect sensors to monitor DC current in the solar panel current, the battery charge current, ...

Why a better current sensor for EVs is advantageous. How a diamond-based quantum sensor may be suitable. Test results for this sensor. Measuring a physical attribute such as voltage or current with ...

Light sensors often use an infrared LED as a light source. Infrared LEDs have a greater intensity than LEDs that emit visible light. And when infrared photodiodes are used the sensors are relatively ...

Can current-sensor ICs win out against the shunt resistor and other passive components? Check out some of the latest offerings on the market in this Products of the Week gallery. For any electronic ...

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 ...

Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to ...

LEDs are a wonderful technology. You put in a little bit of power, and you get out a wonderful amount of light. They’re efficient, cheap, and plentiful. We use them for so much! What you might not ...
