What is a door sensor? Benefits of door sensors with Smarthome

Door sensor is an important device in smart home system. The product is no longer too strange because it is installed to prevent unauthorized entry of strangers into the house. So what is a door sensor? What’s the benefit? Let’s find out with Tnhelearning.edu.vn through the article below!

What is a door sensor?

Door sensor is a very important device in smarthome security system. It has an alarm function that lets you know when someone breaks into your home.

At this time, the sensor will send the received signal to the central controller (HC). HC processes signals and transmits data to phones, computers, ipads, etc. to notify and activate the homeowner’s “anti-theft” device systems to warn.

The device is made of fireproof PP plastic material, compact, only about 36 x 36 x 15mm , weighing about 30g . Composed of two basic parts, forming a unified circuit when in parallel position.

When someone opens the door, these two parts separate and break the circuit, triggering the alarm system.

The principle of operation of the door sensor

Door sensor connects to Wi-Fi and works through a central controller . In addition to the central control unit, this sensor has a structure that includes a switch and a magnet to determine when to open or close the door.

When the switch is closed, the two parts of the magnet are placed close to each other (parallel) and current will flow through .

When the switch is opened, the two magnet components separate, causing the current to stop and the circuit to open. At that time, a notification will be sent to the central control unit to activate the alarm on your phone, and activate the alarm systems in the house.

Door sensor installation instructions

Connect door sensor to WiFi network
