Abstract: The objective of this paper is to develop one better method of watering agricultural field using automation applying basic physical properties of certain chemicals easily available around us. Water, which happens to be a great natural resource, is becoming a scarcity allowing very lean chance to waste it. The approach worked out over here, is a mere approach towards saving it, stopping it from wastage and utilizing it for other more needful purposes. The paper is inspired from the fact rendered that Gypsum suffers certain change in its electrical property in presence of water. We have worked further for the betterment of the response obtained done by some other workers in the same field.

Abstract: An overview of biometrics has been presented in this paper. Biometrics deals with the study of fingerprint, face, iris, voice, signature and hand geometry. Many other modalities are in various stages of development and assessment. Biometric identifiers are the distinctive, measurable characteristics used to label and describe individuals. The two categories of biometric identifiers include physiological and behavioral characteristics. A biometrics would identify by using voice, DNA, hand print or behavior. Behavioral characteristics are related to the behavior of a person, including but not limited to: typing rhythm, gait, and voice.
