Landslides are one of the very serious geologic hazard happens in almost every country around the World. Globally, landslides cause hundreds of thousands of deaths and injuries each year and also Financial Losses. Landslides are mostly unpredictable and occur within a short period of time. To save human life and avoid losses, efficient Technology has to be developed and implemented in high geologically hazardous Areas with low cost. Wireless Sensor Networks Plays a major role in Environment monitoring system. This paper is concerned with the development and implementation of Low cost Autonomous Wireless Sensor Networks based Landslide detection integrated with self-energy harvesting Powered early warning systems (WSN-SEH). WSN-SEH consists of MEMS sensors, Energy harvesting systems, Low power embedded controllers, efficient power Management systems and Super capacitors as storage device.
Electricity can be produced in vehicles fr gases. In a gasoline powered engine about 70 pe fuel's energy is dissipated as waste heat through Thermoelectric generators (TEGs) can directly co energy to electrical energy and can be employed in industry to recover this waste heat energy. We ar efficiency HZ-20 module. This TEG has 71 thermoco electrically in series and thermally in parallel. The are made by using Bismuth Telluride based semicon gives high efficiency at most heat temperatures a strength in tough applications.
The paper presents the technical construction of a robot which is used in cleaning. The term "cleaning" sounds simple, yet we humans face a lot of problems with the disease ridden workplace, a few examples are factories, power plants, Bio-hazard chambers etc., where it is harmful for humans to work. RF signal is used to control this robot. It uses an Induino (micro-controller) for its operation. The mechanical part is the base (rectangular wooden piece) with servo motor and the wheels (plastic wheels) in our case. The material used in mechanical part can be changed according to our prerequisite. The electronic part consisting of the RF signal receiver, Induino and the surveillance Camera are mounted on the base of the robot. The camera acts as the "eye" of the operator transferring live video data wireless either using W-Lan or using cloud computing (in case of monitoring over large distance). The cleaning mechanism includes a normal brush (material of the brush is selected as required) with a servo motor attached to it. This robot not only helps in cleaning rather can be used to monitor things.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
