This sound frequency meter circuit is simple to build and can be constructed in a portable format. In can measure frequencies with a minimum level of 10 mVrms and a maximum frequency of up to 100kHz.

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 ...

[mircemk] had previously built a frequency counter using an Arduino, with a useful range up to 6 MHz. Now, they’ve implemented a new design on a far more powerful STM32 chip that boosts the m… ...

The circuit is a simple digital frequency meter that is made of a frequency-to-voltage converter and an analog-to-digital display converter that can be operatedfrom a single 9-volt battery. The TC7126 ...

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 "Frequency Meter Market - Forecasts from 2023 to 2028" report has been added to ResearchAndMarkets.com's offering.

In an effort to establish measurement methods for a wireless high-capacity information transmission system using the 120 GHz frequency band, one of the study groups in the Technical Examination ...

It comprises a radio frequency meter in which the staff of the sub-station concerned inserts a SIM card prior to installation. After this the meter is connected to a modem installed at the sub ...
