Moutusi Bag received her M. Sc. degree in Instrumentation and Control Engineering from University of Calcutta, India in 2010. She is currently pursuing Ph.D. in Engineering at Jadavpur University, India. Her research interests are in the area of daylight harvesting for indoor lighting control and solar based lighting system

Saswati Mazumdar, M.E., Ph.D., Professor of Electrical Engineering, Jadavpur University (JU), Kolkata, India. She has 35 years of experience in lighting research and teaching. Developed a modernized illumination engineering laboratory in electrical engineering department, Jadavpur University. Have founded two masters’ courses on illumination engineering (daytime) and illumination technology and design (evening) in Jadavpur University. Executed a large number of R&D and consultancy projects in the illumination field

Kalyan Kumar Roy, Ph.D. He is currently a consultant to industries manufacturing electronic systems. His primary research interests include control of power electronic converters, embedded control and instrumentation, solar photovoltaic conversion, and vehicular electronics

A cost-effective two-wire industrial standard illuminance sensor (4–20) mA has been proposed. It can be used for daylight harvesting control of indoor illuminance and other applications. The basic sensor used is a cadmium sulphide (CdS) light dependent resistor, whose relative spectral characteristic almost corresponds to the human eye. The method of sensor calibration has been presented and static and dynamic performance characteristics of the sensor have been experimentally determined.
