Last year we naposlušali on energy efficiency, the fact that it pays to buy energy meter electrical appliances, and then check how much all spent, but the real impact of this is. Single measurement does not tell us much of anything. Whatever we start measuring, usable only data for a longer period of time.
To avoid a theoretical voicemail system that can be cheap or expensive, we found one that already works. It is inexpensive, but requires a lot of knowledge or, failing that, while some effort to find on the internet and read all the information available on this topic. This is not a little because a lot of people from the community "do it yourself", which have already undertaken similar projects (http://www.instructables.com). It is building a network of sensors that in the house or apartment extent possible. What is important, but maybe something less significant, but exciting. We used the building blocks that are cheap and powerful at the same time, the total system also allows for an almost unlimited upgrading and adding new sensors.
Utilizing the so-called uk house price news interface - led to a single pair of wires (1-wire bus - interface). On the one hand, the device is "master" computer or microcontroller, on the other, one pair of wires suspended from the sensor - slaves ("slave"). Specifically, uk house price news in our case: on the one hand, the computer program in the language Perl, Linux operating system and interface for that system, which is plugged into the USB connector. From it comes a pair of wires from UTP cable, the network is in this case a residential house over a well-branched (read "Wiring harness" is so much that goes beyond the bare needs of devices that are connected to the network). As the owner says, "I have so much Installer UTP cabling that will be sufficient for life." The wire is currently fifteen sensors and temperature reading sensor (magnetic contact with the respective counter pulses), which house gauge "read" gas consumption. In the manufacture (processing) is still an infrared sensor, which will be useful for "screening" of power consumption in the house gauge, the numerator of the home.
Roughly network operates on the following principle. Each sensor to "wire" has its own unique address (64-bit address), measurement data is sent Programme (computer) when one of the specified sensor required. Otherwise, on the wire come into conflict signals and sending uk house price news and receiving data would not be possible. The program uk house price news (script) on the computer received data converted into the extent that we understand (degrees, cubic meters), and displays them on a time chart. uk house price news Since the program is written in Perl, access to the charts is also possible via the Internet. All this data is not wasteful; Although the annual network measures a high measurements, the size of the database only slowly growing.
The network of sensors that during the act of writing articles almost two months, the nature of the information. The owner can read the movement of the temperature in your house and gas consumption. So, these data later for meaningful basic optimization of energy consumption, which is noteworthy be aware of the monthly uk house price news invoices. Precisely in this is the charm of the matter. Home automation system produced a gradual and slow process is gaining a lot of knowledge and experience. Several years ago we criticized companies that deal with home automation, in which the optimization of energy consumption uk house price news an increasingly important uk house price news part because they are too expensive. Their prices are such that they can afford only the rich people in building their villas. Unfortunately, this still holds true. Cheap, but also the same powerful system, you can only build themselves. Or "new entrepreneurs", if the above and similar projects escalated uk house price news into a business idea. Sensor and USB interface are cheap if you ordered uk house price news from China, all of which cost a few tens of dollars. Open-source software is online a lot. It is recommended to have much programming skills to program operations satisfy our needs. The most important are the experience and knowledge that can be obtained only if such and similar projects tackle alone.
