Item Solar Auto Irrigation System (SAIS)(University of Management and Technology, 2016) Naeem Shehzad; Abdur Rehman Siddqui; Rizwan AyubAgriculture is an important source in a country like Pakistanand many Pakistani's earn through farming. The weather in Pakistankeeps on change and people some time face lack of rain which result in wastage of crops. Also there are some lands in which the water is available in excess. So to come across this problem we have designed a system which control the excess water in the crops and stops the pumps when the water is not required in the crop. Basically this system is built and undergoes to a process and Works on commands given by the Arduino connected. In this system we are using the power from solar panels as there is shortage of electricity and Pakistanis in Energy crisis as well. Using this system helps to use Alternate source of energy and fulfill shortage of electricity. The sensors are connected in the crops field and keeps on checking the moisture of the field as soon as the crop requires the water the sensors will send the command to Arduino which starts the functioning of the pumps and as soon as the crops are irrigated with the water the Pump will be shut down and the excess to water will be finished. Furthermore description of the system is explained in the report below. Moreover a GSM module is also used which will inform the farmer about the on/off of the pump and flow of water through an SMS.Item Space based solar power generation using a distributed network of satellite(UNIVERSITY OF MANAGEMENT AND TECHNOLOGY, 2015) Zunaira Nazeer AhmedSpace Based Solar Power generation proposed a new technique to fulfill the increasing energy demand .It has high efficiency as compared to the earth based solar power generation. In this technique we will established satellite constellation at the geo synchrouns earth orbit (GEO) .At this constellation solar panel assembly is attached which capture energy from the sun at GEO solar energy will not face any hindrance as in earth based solar power generation(EBSP) for instance in EBSP maximum energy will not reach to the earth due to atmospheric attenuation , weather condition .Moreover in SBSP it will not face any such type of hurdle and at GEO 30% maximum solar energy is present .When solar energy captured by the satellite constellation it will transmitted to the earth with the help of WPT technique . In this thesis mainly concentrate on the (i) Satellite constellation architecture (ii) Power Transmission technique through space (iii) Device which used to transmit this power .In previous SBSP approach power is transmitted through the Laser transmission technique .But in this thesis we are using Wireless Power Transmission (WPT) technique to send microwave power to the earth. Research on the best material for solar panel which has maximum conversion efficiency, Research on different alternatives of SPS (Solar Power Satellite), research on different type of transmission antenna has been done in this thesis.
