Application of Iot with Motion Sensor for Smart Learning Environment

Abstract

Considering the estimate of the potential system in the classroom, lights and fan control is expected to be performed in three modules. Thus, in the case of light and ventilator power, occupancy sensor is used to estimate the amount of output voltage increases in the diode while the rotational speed increases simultaneously. Motion sensors are common where safety and energy efficiency are concerned. They can be used for burglary alarms or surveillance cameras, which activate such devices when it detects nearby motion. This can be an energy saver by turning off lights in a building as it no longer detects activity and is commonly used in office buildings and toilets. The PIR is a motion sensor that you might have seen when you enter a bathroom or office space, normally with a white mask. They are lightweight, low powered, simple to use and low cost. The way it detects motion is by sensing the temperature differences between the surroundings PIRs are fitted with a passive sensors level of infrared radiation –all emits some low-level radiations, but a human body emits good heat. This triggers a pulse when the sensor senses a different shift between the two slots which is what it detects as ‘movement’ Technology is available that combines both PIR and microwave sensors to have less false alarms, a sudden increase in room temperature will cause the PIR to go off while wind will push an object and activate the microwave sensor.
