CHAPTER 1 ORGANIZATION PROFILE Snow and Avalanche Study Establishment (SASE) is a laboratory of the Defense Research & Development Organization (DRDO). Located at CHANDIGARH its primary function is research in the field of snow and avalanches to provide avalanche control measures and forecasting support to Armed forces. SASE registered steady growth from 1971 to 1977 and role of SASE was enlarged with the constitution of Advisory Committee. Avalanche forecasting‚ Artificial

Adaption of wireless sensor network for farming industries This article is present the solution that implements real-time health monitoring using alternative low-cost ‚ low power consumption wireless sensor nodes. To achieve this goal‚ a variety of factors that associated with cheap ‚ lower power consumption sensor nodes on the radio connectivity is presented. ( MICHAEL GILROY ‚ 2009) Various researchers have been using wireless network in a form as neck mounted sensory collar to track animals’

for use as a proximity sensor 2 AT42QT1010 and AT42QT1011 The AT42QT1010 and AT42QT1011 are identical apart from their behavior when the sensor is “in detect” for an extended period. The AT42QT1010 has a “maximum on” duration of ~ 60s. If there is an obstruction on the sensor‚ the device output will go low after the “maximum on” detection period‚ so that subsequent touches can be detected. The AT42QT1011 has no timer and the device will remain on whilst the sensor is activate. Speed Settings

Objectives: The Objective of this experiment is to control the level water by feedback transducer‚ and get familiar with the action of PID. Theory: Measurement of level and pressure (analog type output) with pressure and level measurements‚ the pressure sensor set at the bottom of the vertical column of unit ty3oa/ev is used. Definition of an Analog Variable: An analog measurement ring permits the generation of a D.C. voltage which behavior follows the water level in the column; this means that each
