I got a couple of INA 219 modules from an online seller overseas. I was looking for a different dc current sensor module to start a small battery charger project, so I welcomed them. The INA219 based ...

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 ...

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, ...
