We have a wide range of options in terms of home automation in our homes. There are many devices that help us in our daily lives and some are really cheap and easy to use. In this article we are going to talk about one of them that can be very useful for many users. It is a device that detects when a window or door is opened. Very interesting to save energy, for example. You will see that it is very easy to install and use.
Open window or door sensor
To save electricity at home, one of the tips you will always see is to control when doors and windows are opened. Think for example of winter, when it is very cold outside and you turn on the heating. If you leave the window open, you will have to consume more electricity or gas in order to heat a room. The same if you open a door.
To prevent this from happening, as well as detect possible intruders in the home, prevent your pet from escaping or having any problem by leaving a door or window open, you can use a sensor . It is a device that you are going to place on the door or window that interests you and notifies you as soon as it detects that it has been opened.
This type of device is compatible with Alexa and Google Home . It sends an alert to your mobile phone if it detects that a window or door has been opened. Its operation is very simple, since basically it is a sensor that you connect to the door and another to the door frame (the fixed part, the one that does not open). As soon as the door is separated from the frame, it detects that it is open. The sensor and magnet are less than 10mm apart, so it’s sensitive as soon as they’re apart.
It works through Wi-Fi using the 2.4 GHz band. Although it does not have a siren or alarm, it does send an alert message to the mobile in a matter of seconds once it has detected that a door or window has been opened .
Very useful for many situations
If you are wondering what use a sensor has to see if the door or window has been opened, the truth is that you will find several. One of them is to avoid unnecessary energy consumption . For example, prevent a window from opening and entering cold or heat. If you are going to put on the air conditioning or heating, it is important to prevent this from happening.
It is also useful if you have pets, for example. Due to an oversight you have been able to leave a door or window ajar and you have been able to open it to get out. By receiving an alert on your mobile , you can take action as soon as possible so that no problem occurs.
In addition, although it is not its main function, it will also notify you in case there are intruders . After all, it will detect that a window or door has been opened improperly and it could have been by an intruder. When you receive a message on your mobile in a matter of seconds (from 2 to 8 normally) you can take action immediately.
In short, as you can see, you can use home automation to know at all times when a door or window has been opened. You can put it anywhere, since its installation is simple and you only need both devices to be close (the sensor and the magnet) for it to work and to have access to a Wi-Fi network.
