Abstract

Frequency is a fundamental parameter in the field of Electronic technology. As a basic measuring instrument, the digital frequency meter is extensively applied for its features such as high precision, fast speed, digital display. This paper describes a very simple and data transmittable design of a Digital Frequency Meter using a PIC microcontroller with some simple functions. This digital frequency meter has a range of frequency measurement from 1Hz to 100kHz and a resolution of 1hz and accuracy less than 0.5%. Digital Frequency Meter measures the frequency and displays its data on 1602 LCD screen with a unit in thousands(kHz); the usage of microcontroller enables it to toggle measuring mode, pause the data display and transmit data to other microcontrollers for extra uses.
