Most of the work reported on implementation of Remote labs has been related to labs on control systems and to a certain extent to labs on Electronics Engineering. Therefore, in this paper we have described the design and implementation of a remote experimental setup for performing experiments on Sensors, specifically Temperature Sensors, from a remote location. The traditional experimental setup was interfaced with a Personal Computer, which acts as the Lab server, using data acquisition card (DAQ Card) and software programs written in LabVIEW. The PC was connected to the LAN / Internet and the experiment was published on the network using the LabVIEW Web publishing and Internet Tool box and G and Web Servers. Thus the experiment has been made accessible to anyone, over a TCP/IP network, with a standard Web Browser, relevant plug-in and permission. The aim was to control and change the temperature of the bath in which the temperature sensors were inserted for their characterization, and further collect data from the resulting change in the temperature sensor’s output. In Temperature Sensors characterization experiments, the temperature was varied over their working range on an aluminum plate and the output voltages of the Temperature Sensors (including the signal conditioner) were recorded for each variation in temperature. The remote client could control the bath’s temperature and monitor the temperature of the bath and transducers’ output in real time.
