The security industry has developed for thirty years, which has becomes a part in people’s life. A humidity sensor is used to detect, measure & report both air temperature as well as moisture. Humidity plays an essential role in the environment as well as the human body. The list of humidity sensor based projects for engineering students is listed below. I just want to do some Mini projects based on electrical and electronics.I am a btech 2nd year student from EEEso can you please tell some mini projects. Arc welding is widely used method of joining metal parts. In this, source of heat is an electric arc. An arc is produced between an anode (positive pole of direct current power supply) and the cathode (negative pole). Arc welding is done by producing an arc between the work to be welded and the tip of the electrode. This type of welding has the advantages of(i) less heat loss and(ii)less oxidation as compared to oxyacetylene flame. An electric arc is an electric discharge in gases, accompanied by high heat and a bright glow. As leading technology forecaster, Daniel Burrus, explains, IoT’s true value lies in the fact that these devices will be able to collect real-time data, and allow us to leverage information and turn it into action. The aim of this programme is to provide students with ample time to make independent contributions to scientific knowledge in areas of Computational Mathematics, Mathematical Statistics and Financial Mathematics. On completion of the programme, students will be capable of leading research at universities or take up positions in research institutions, in industry or in academia. In 1912 Rosenwald was asked to serve on the Board of Directors of Tuskegee Institute, a position he held for the rest of his life. Rosenwald so adequately endowed Tuskegee that Washington could now spend less time traveling to seek funding. This allowed him to devote more time towards the management of the school. Later in 1912, Rosenwald provided funds for a pilot program involving six new small schools in rural Alabama, which were designed, constructed and opened in 1913 and 1914 and overseen by Tuskegee. The model proving successful, Rosenwald established The Rosenwald Fund, to replicate it all over the South. The school building program was one of its largest programs. Using state-of-the-art architectural plans initially drawn by professors at Tuskegee Institute, the Rosenwald Fund spent over four million dollars to help build 4,977 schools, 217 teachers’ homes, and 163 shop buildings in 883 counties in 15 states, from Maryland to Texas. The Rosenwald Fund used a system of matching grants, and black communities raised more than $4.7 million to aid the construction of these schools which became known as Rosenwald Schools. By 1932, the facilities could accommodate one third of all African American children in Southern U.S. schools.
