CBSE Science Fair Exhibition Project, “ PIR (passive infrared) sensor” Theme “Natural Resource & their Conservation” for Class 9, Class 10 and 12

Project Name : PIR (passive infrared) sensor

Theme Name : Natural Resource & their Conservation

Scientific Principles:

1. PIR SENSOR: PIR (passive infrared) sensor is a technology and an electronic sensor that measures infrared light radiating fromobjects in its field of view.

2. Piezo technology: Piezo electricity is the electric charge that accumulates in certain solid materials in response to applied mechanical stress.

3. Solar Pillars: As the pillars get heated up in the corridors the can be replaced by solar pillars made of photovoltaic cells.

4. Piezo in the staircase: Again,here we depict the efficiency of the piezo system by using it to generate energy due to the constant mechanical stress on these.

5. Piezo in the playground: With the help of rotator wheels underneath and on the sides of a merry go round and slide energy is generated by rotatory motion.

Procedure:

1. An audit is to be conducted keeping in mind the energy conserving and generating techniques.

2. With this audit the physical areas will be selected and marked for the energy conserving and generating points as per the physical location of the area as well as the technical position of that area.

3. We will make a model of both energy generating and conserving techniques in a school.

Unique features of the exhibit: It highlights the efficiency of Piezo system by incorporating it in places like speed breakers, on the staircase and in the benches. It makes use of the PIR sensors combined with the idea of the Piezo system. Together they do not require much energy for execution and is applicable in all the domains of life.

Further Scope of the Exhibit: The exhibit though seems to be a small step towards energy generation and conservation but if executed in the right manner can prove to be very fruitful in the future because tomorrow will bring about a change.

Name of the School: Sacred Heart Sr. Sec. School, Sec.26, Chandigarh.
