A Langmuir probe is being developed for measurement of electron densities, ion densities, and electron temperatures in the MARS ionosphere. This article describes how a Langmuir Probe can be used to study ionosphere irregularities. It begins with the basic principle of the Langmuir Probe, the ionospheric regions where it can be used, various sizes and shapes of the Langmuir Probe sensor. Here In this paper, we present the design and how implementation of Langmuir Probe instrument. I have prepared a block diagram of Langmuir Probe (see figure 2). The Langmuir probe experiment consists of a cylindrical sensor. A conducting sensor called probe is exposed to the medium under study and the current collected by the probe is measured to study various plasma parameters. The probe can be kept ambient plasma potential or given a negative voltage (to collect ion current) or a positive voltage (To collect electron current).After the current and voltage charatertics we analyzed plasma parameters. The operational amplifier will be connected with the sensor. A floating sweep voltage supply will also be applied to the sensor for collect current. Here after than collected current is goes to differential amplifier. The differential amplifier is amplifying the difference between both signals. Later we will use low pass filter for remove the un-wanted frequency of signal. Here the analog to digital convector for generating a digital signal for processing. The signal output will be displayed on LCD display screen by using micro-controller.

Keywords- Sensor, ADC, Sweep voltage, Amplifier, Differential amplifier Low pass filter, micro-controller, LCD display.
