BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Lights, fans and other electrical appliances keep on working unnecessarily even when no person is present in room or other similar space causing a significant loss of electricity along with capital. Therefore, saving energy in form of the electricity is essential. Cost of energy or electricity consumption for the electrical appliances like light and fan is high. Use of electrical appliance is dependent on population and accordingly the cost of electricity also increases with increase in number of electrical appliance. So, making proper use of the electrical appliance by turning them on and off as per requirement is must. There is a need for a solution that help in saving electricity efficiently by using the electrical appliance as per the requirement.
[0004] Existing solutions can include sensor based system like infrared or passive infrared sensor which emits rays, however such sensors cannot track accurate and precise motion of a person due to noise present around and cannot differentiate between the person and an moving object or a lifeless thing. Another solution includes pyroelectric sensor, which can detect the motion of the person based on principle of detecting range component of infrared rays but measurement signal is lost during times of no movement of person. Furthermore, for a long range field of view, sensitivity of such sensor decreases.
[0005] There is a need to overcome above mentioned problem of prior art by bringing a solution that is precise and accurate for detecting movement or motion associated with the person and continue to generate a measurement signal during times of no movement and enables saving electricity and money.
