This simple micro ampere meter circuit can help in measuring small currents in five ranges: from 1 µA to 10 mA. The meter is working in this way: the current being measured Ix shifts the input voltage ...

This LC meter circuit can measure coils and capacitors. When Lx or Cx is connected in the circuit the oscillator frequency will decrease and this decrease is measured by a frequency-voltage converter ...

A nanopower voltage regulator was added to the water-meter circuit. Adding this IC can significantly extend the battery life—life extensions of 20% and higher are easily possible.

They can be used to test car batteries, wall outlets, wires, circuits and other electronics. Multimeters can help beginners test comfortably without the need call an electrician. Here are the best ...

The device measures voltage and current and displays them, along with the calculated power, on the small 0.5″ OLED display. The circuit is built around an ATmega328.

The Tiny V/A meter can be used in a variety of applications. For instance, it can be employed in educational settings to teach students about electrical measurements and circuit design.

Voltage measurements are within 1% of conventional contact probing, power below 10W can be resolved, and complex loads like triac dimmers can be handled. More information on the algorithms is ...

Smart meter stock hits 10% upper circuit after reporting 100% YoY increase in revenue. Story by Shivani Singh ... Vacuum Circuit Breaker, Reactor, Residual Voltage Transformer and more.
