The title says it all – this article describes a microcontroller-compatible current sensor module you can build yourself, using an inexpensive 8-pin chip as an ‘active shunt’ for measuring ac/dc ...

When taking measurements from analog sensors located at long distances, voltage drops and noise can affect precision of the readings. Therefore, a voltage-to-current (V/I) module is needed to transmit ...

In all but the most pedestrian of cases, you really should consider some form of input protection between your sensors and your computational platform. In my “Beginner’s Guide to Sensor Interfacing ...

In Part 1, we covered the basics ofsensors and the characteristics youmust keep in mind when using them in designs. However, there isan enormous range of specialist sensors developed for ...

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 I/O capabilities built into most microcontrollers make it easy to measure the analog world. Say you want to build a data logger for temperature. All you need to do is get some kind of sensor that ...

Miniature smart sensor combines 3-axis digital accelerometer with embedded microcontroller, operating as sensor hub that runs sensor-fusion algorithms, together in ultra-compact package called iNEMO-A ...
