Smart Gas Leak Detector

Information about project According to world statistics, mortality due to carbon monoxide poisoning is in second place after alcohol poisoning. For example, in America, about 400 people die every year from carbon monoxide poisoning. In Kazakhstan, mortality from poisoning with liquefied and natural gas is over 20 people a year. The causes of poisoning are often violations of the operation of furnace equipment and household gas appliances. A carbon monoxide detector (miniature device) for a home can help to warn the owners in a timely manner about possible dangers and eliminate negative consequences.This tutorial proposes an Arduino based wireless gas safety device design. The device is intended for use in the home where natural gas and LPG fueled appliances and heaters can be a source of risk.

Tactile Periodic table of chemical elements

Information about project It is known that people with disabilities face various social problems, especially in the field of education. But every person on our planet can do more and turn limited possibilities into limitless ones with the help of innovative and information technologies. In this project, students explore a social issue regarding teaching aids for visually impaired people. They will study and apply the Braille font for a tactile description of the periodic system of chemical elements of D.I. Mendeleev for people with visual impairment. In addition, 3D modeling (using the SketchUp program) and 3D printing will be used to make tactile educational material.

The impact of household chemicals on people and the environment

Project Information Currently, it is difficult to imagine life without household chemicals at home. Since people are exposed to household chemicals on a daily basis, they have to be aware of their harm to the human body and the environment. In this project, students conduct research on household chemicals by conducting various experiments.
