As in the process control system it is very often required to record the various process parameters like temperature, pressure, flow, voltage, current, strain etc..And this parameter values will be used for maintaining the process control system automatically. Sensing and recording of physical parameters plays an important role in many industries. In the past analog devices were used for measurement of such parameters. A simple technique combining analog and digital circuit theory together with programming techniques has been used in this paper to design a temperature and pressure sensing system. The sensor’s analog signal is applied to a micro-controller based data logger for storage purposes.

The main objective of our project is to log and store the data and by using this data we can analyze the performance of the systems. Generally in any process industries along with the supervision of the parameters, analyzing the system performance is also an important task .So, in order to analyze the performance we need to acquire the data regarding that particular device. For this purpose we use data loggers.
In this project the physical quantities that we are measuring are temperature, pressure and liquid level. All the three parameters are sensed by using particular sensors, temperature is measured by using temperature transducer, pressure by using multi turn pot and liquid level is sensed by using limit switch.
