This frequency meter project squeezes a lot of performance out of the ATtiny2313 microcontroller. That chip does all of the work, measuring the frequency on the input pin as well as multiplexing the ...

The device is a simple, small, and cheap frequency meter with out any hard to find components to be able to measure frequencies up to 40 MHz while having below 1% errors. Most of the analog and ...

The project was developed for measuring frequencies from 5Hz to 500kHz as it was based on the AT89C52 microcontroller. This 500kHz frequency meter is suitable for tracing and debugging most of the ...

Flow sensors are useful tools for collecting data on the rate of liquid usage, but they need a device to display the data they collect. This three digit frequency meter was designed by [Turbokeu] to ...

The Wood Dale City Council has agreed to buy 344 radio frequency water meters at a cost of $50,000 for a pilot program aimed at collecting data to determine whether the technology increases the ...

The mobile technology will now help the power department to detect electricity theft. The department plans to install radio frequency meters in electronic meters installed in homes. The device, which ...

Keysight Technologies today introduced three low-frequency options for its E4982A LCR meter. With these new options, the E4982A is suited for RF inductor, coil, and EMI filter manufacturers that are ...
