Remote temperature sensor - Essay Example

Instrumentation and control are a vital part of any feedback automated system. Research and control data must be collected frequently and recorded as soon as it is collected in order to draw conclusive results from it. The results obtained can be used for controlling and monitoring of many industrial applications or may give results towards an experiment that is being carried out. This project consists of a remote temperature sensor. It comprises of a different sensors located at ten different geographical areas.

The sensors measure the temperature of the surrounding and send it after every ten minutes to a computer located at a meteorological department.In this project, a metrological data recording center requires the collection of data from ten different towns located within a given country. The metrological department needs to evaluate the temperatures of the ten aforementioned towns in order to calculate, determine and forecast the weather. Previously, the metrological department has been relying on data collected manually by technicians and it is then sent to the headquarter for evaluation.

This has been problematic due to the fact that the data is unreliable, inaccurate, not collected within the stipulated time window, inconsistent, inefficient and always late. This has promoted the metrological department to collect the data using a set of remote temperature sensors located at these major towns.The central computer system receives these signals after every ten minutes and records them on a computer database. . n and configuration of the remote temperature sensor and its microcontroller unit, installation of this unit, software design as well as the assembly of the whole unit.

After assembly, the equipment will be tested on its capability to log data from ten different locations. The data will be received to the computer unit through a broadband modem. Both the internet of GSM/GPRS system will be applied. This will aid in accurate location of the given sensor. It is hoped that the system will enable accurate, reliable, efficient and effective data collection as well as its manipulation, tabulation and presentation of the temperature information on the computer display unit.
