Abstract:

None conservative use is observed among the Bangladesh people in non-conservative utilization of public power supply. This increases power bills and may hinders a nation from diverting power to industrial areas, limiting the process of industrialization and waste of energy. Individuals are often observed power on the lightings, cooling systems when not needed at homes, offices and marketable centers. To head off these, this paper presents development of automatic switch using passive infrared sensor and solid-state relay for day and night detection (LDR). The objective of this project is to cut out the electromagnetic relays which may break down as a result of carbon associating resulting from incurving in alive designs with solid state relay. Also, the system is to conserve energy more by ensuring that light is not powered on during the day time except in cases of darkness. The circuit was designed using components such as; Light Dependent resistor (LDR) sensor, power supply, PIR sensor, Microcontroller and SSR, as showed in the circuit figures 8 and 10. The system SSR for switching, LDR to detect night and day and PIR for human detection. The system was tested and worked perfectly. It helped to economize energy.

Description:

All over the globe, it is also seen as a means of development of nations However, in third world countries, the barrier or slow rise in development above all in industrialization may be hinged mainly on the careless attitude of individuals in energy management and consumption at home above all 47-powering cooling and lighting systems in unused places. Electricity has been found to be the most clean and easy way for transportation of source of energy. This is because of its rules in the supplying of energy among other forms of transportation. As a result of this, power can’t be displeasing to industrial areas so as to fulfill production. In 2008, Sambo in a study, Equalize Electricity supply with requirement in Nigeria affirmed Oyedepo in 2012, revealed the much energy potential in Nigeria. The study maintained that the use of generator is on the increase as a result of the demand for electric energy which isn’t sufficient. This however, hamper the economy of a nation as it mounts pressure on the oil sector and reduces foreign exchange possibilities as a result of increase in the consumption of oil product locally. To avoidance this ill, this paper presents development of automatic switch using PIR and SSR for day and night detection as a means of energy conservation at home. Efforts to increase protection attitude among individuals towards energy has been on the pursuit for a long time. This has spurned technology in the direction of the production of low wattage bulbs. In recent years, LED’s are used to produce electric bulbs because of its landmark to give output of an appreciable lumen with less power. All these efforts only reduce power expense and not the wastes. Suman et al, developed a home monitoring system for disable and wise where he used PIR among other sensors to sense intruder and then sends an alert via a GSM module. Ajay et al, worked on Motion Detection using PIR sensor and showed how an alarm blares when an intruder is sensed, also Okokpujie et al developed a model for automatic control of home appliances using DTMF techniques.
