Currently, almost every resident has his own country country house. As a rule, most of the time the dacha is empty, people live in cities, and come to dachas only on weekends or during vacations. In the country, often not only old, unnecessary things are stored, but there are also many useful things that are useful in everyday life, as well as many valuable things and equipment in the house. But what happens in the country when it is empty?
While the cottage is empty, without owners, it can be of great interest to thieves. Indeed, in our time it is not so difficult to open the castle and take out a couple of expensive things from the house. How to avoid this, because not everyone will find the time to come to the cottage and check the house every day?
While the owners of the cottages work in the city, your home can reliably protect the GSM alarm system. Installing such an alarm in the country is the most correct and reasonable solution. And in order not to waste time searching and a lot of money to buy such an alarm, you can make it and install it yourself.
To create a GSM alarm you need:
- An old unnecessary mobile phone with buttons (probably you have these lying around in an old chest of drawers or on the very top shelf);
- Magnet (sold in any store);
- Sealed contact - hermecon (normal or with three contacts);
- switch and wires;
- soldering iron.
And besides this, you still need to have some minimal knowledge in electronics and have a little time and patience.
So, the first and easiest thing to do is set up a quick dial call to your current phone number. The first step is ready.
Further, the task is a little more complicated, but if you follow the instructions, then everything will surely work out. At this stage, you need to disassemble the mobile phone and carefully expose the board under the keyboard.
And then connect the device. There are two connection schemes. Before choosing a scheme, you need to decide: on the mobile phone, the call and failure buttons are one key or different.
Scheme one.If the call and fault buttons are one button, then one wire must be soldered to this key, and the second to the digital button, which is assigned a quick call. This is done with a soldering iron. Hermecon is used in this case with a standard closure system.
Scheme two. If the call and fault buttons are two different keys, then you will have to solder an additional wire to the second button (one of the wires will be common). In this case, a hermecon with three contacts will be used.
Having created the circuit according to the scheme, we proceed to the third stage. It is necessary to install a magnet on the front door and set up the germone so that the chain stays broken when touched.
The principle of operation of such an alarm is that when the door opens, the circuit closes and the phone rings on a quick call to your phone number.
Where to install such an alarm is a personal matter for everyone. Most importantly, it should be protected from prying eyes and moisture.
