Using a 25-µ? shunt, the SFP101 current, voltage, and temperature measurement IC from Sendyne typically achieves a current measurement accuracy to within ±0.05%, while operating over the automotive ...

The idea is simple enough: just place a INA219 current sensor between the power supply and the microcontroller under observation, and record the resulting measurements as it goes about its business.

INA219 Module & Arduino – First Test. Admittedly, there is nothing new or special about the INA219 module as there are countless tutorials/projects out there that exploit its ability to measure both ...

Closer Look at the Current Sensor. The TMCS1123 develops an output voltage proportional to an input current up to 75 A continuous. The five available sensitivity options include 25, 50, 75, 100 ...

Like many hackers, [Matthias Wandel] has a penchant for measuring the world around him, and quantifying the goings-on in his home is a bit of a hobby. And so when it came time to sense the current … ...
