System monitoring feedback in cinemas and harvesting energy of the air conditioning condenser

Abstract

Abstract. Our article monitors the degree of emotional involvement of the audience in the action film in theaters by measuring the concentration of CO2. The software performs data processing obtained dispersion sensors and displays data during the film. The software will also trigger the start of the air conditioning condenser where we can get harvesting energy by installing a piezoelectric device. Useful energy can be recovered from various waste produced in cinema. The time lag between actions and changes in environmental systems determines that decisions made now will affect subsequent generations and the future of our environment.

A Learning Management System Enhanced with Internet of Things Applications

“…CO 2 gas sensors could be placed in the tubes of the air conditioning system to measure the CO 2 concentration in the classroom at different time intervals. By using the algorithm proposed in (Pop et al, 2017), the level of concentration and excitement in the classroom can be measured from the differences in the CO 2 concentration readings. When students are using classroom laptops or tablets, smart headphones such as Mindset (Mindset, 2017) can be used to measure the focus level of the student by means of electroencephalography (EEG) sensors that are built-in within the headphones.…”
