dc.description.abstractThe research work deals with the development of sensors in the field of optomechatronics and agro-electronics to measure electrical and nonelectrical quantities. The development aims to. produce sensors that are low in cost and have simple design with good order of accuracy, precision and can be used in remote places. The first sensor employs electro-optic technique for the remote measurement of temperature to assess the safety and stability of different types of systems. It has an accuracy better than 1%, and is able to measure temperature up to 30°C. The second sensor has been developed for the remote measurement of electrical current using magneto-optic devices. It has been successfully used for the measurement of currents up to 60 A. The third sensor, using the thermo-optic technique, has been constructed for the remote measurement of current. The output has been shown to have a standard deviation better than 0.5% under hazardous conditions. Next, in the field of agro electronics, impedance spectrometry has been used to characterize fruits and vegetables non-destructively. The basic sensor used for this application is a probe system developed to aid the measurement of impedance non-invasively. Finally, a fibre-optic sensor has been developed for detection of adulteration in edible oils by determining the cloud point of the oil under test. The optical sensor together with the temperature sensor and microcontroller is used to obtain the cloud point measurement. It can be used economically for qualitative analysis of adulterated oils in a short interval of time.en_US
