As the measured scope of frequency ranging from 1Hz to 150MHz, resolution has reached 1Hz. 　　This frequency counter provides a simple, easy to use measuring instrument. Compared to the frequency counter currently found from the market, this model is small in size and cheaper in price. Equipped with LCM, the frequency can be found instantly. MSP430G2553 can also be linked to terminal software on the computer, in that way, the frequency value can be stored via the software and further be calculated. 　　The frequency counter from this research not only can be used as measuring equipment but also be used collectively with other measuring equipment which requires higher precision. For example, temperature, humidity, pressure, gas measurement can all use frequency counter to obtain the figures, which saves the effort of using other bigger frequency calculator. This makes the utilization more convenient.
