How Does a Door Sensor Work?

While there are several different types and styles of door alarm sensors, most use a reed switch and a magnet to determine when a door is open or closed. Reed switches are used in countless devices, from doorbells to laptops, and rely on a set of electrical connectors. The switch is closed when the two parts are sitting close to one another, and an electric current can flow. When the switch opens, the two parts separate, causing the electrical current to stop and the circuit to deactivate. When you add a door sensor into your home security system, the device will come with both pieces: a reed switch and a magnet. One piece attaches on the door frame, and the other attaches parallel to the first piece on the door itself. The two parts create a closed circuit when the door is shut. As the door opens, the magnet and switch separate, breaking the circuit. When the circuit breaks, the sensor signals the central control panel.

What words do have to spell when said around your dog?

It is not so bad now but around my border collie Rex you would have to spell bath when it was time for him to get one. He used to be so bad. He would put his paws on the door frame so you could not bring him in the bath room. He would not go in the bath room for anything. We would try throwing a toy in there but after the first time of that happening and the door getting shut behind him he learned fast. He has gotten better now. We tend to give him baths outside and it is easier to trick him into it. The thing was once he got into the tub he was perfect angel, he would not more or try to get out until you were done. You could even leave the bathroom and come back and he would still be in the tub. He had a defeated look on his face which made you feel sad
