The following invention refers to an autonomous electronic system for the economisation of electrical energy for rented and privately owned spaces and is comprised of a small detector device, microscopic detectable electronic component (placed in a keychain) and circuit connecting to the circuit breaker mains. In accordance with the suggested application of the invention, the system can be installed in hotel rooms. The detector is internally placed in each area next to the entrance. Upon entering, the resident finding the lights off, places the key to his room on a lighted system panel, which is accompanied by the electronic system. The detector automatically supplies current to that area and the resident can make use of the switches. When he/she leaves, taking the keychain, the system then, after a set time, shuts down the electricity supply, turning off the lights in the area. The system can turn off the power supply -other than the lighting- and appliances such as air conditioners, TV's, etc. This system economises at least 40 percent on consumption of electrical current and is autonomous (without batteries) at the same time, reliable because of the absence of mechanical parts (switches etc.) and can be placed in all areas (even a posteriori) since its installation is extremely easy. |
