- The new concept of Langmuir probe has been developed for measurement of electron densities, ion densities, and electron temperatures in the MARS ionosphere. Here this article we discuss how a Langmuir Probe can be used to study mars ionosphere. It works on basic principle of the Langmuir Probe. Here in this paper we describe the about design, implementation and laboratory result. We have prepped flow of the architecture of this system (see figure1).The basic principle of the Langmuir Probe where it can be used for find out the plasma parameters. The Langmuir Probe experiment consist gold coated cylindrical sensor is input stage of the system. We apply to sweep voltage to sensor for generating current. The sensor has kept in plasma if we apply the positive current sensor exposed with negative ion the collect the current. After the current voltage charatertics we analyzed the plasma parameters like electron density, ion density, electron temperature ect. The feedback operational amplifier has been connected with the sensor. It has input stage of the experiment system. Then output of operational amplifier is goes to differential amplifier. The differential amplifier is amplifying the difference between both signals. Later we have been used low pass filter for remove the un-wanted frequency of signal. Here the analog to digital convertor for generating a digital signal for processing. Finally analog to digital convertor is interface with microcontroller, here microcontroller is also interface with LCD. So by using microcontroller we have been display result on elemety display.

Keywords- - Sweep voltage, ADC, Sensor, Operational Amplifier, Low pass filter, microcontroller, LCD display, Differential amplifier
