In today’s society, many places are becoming increasingly chaotic, which makes it important to protect family members. Smart door sensors are very effective in improving house safety. When the house or window is opened, we will receive a mobile reminder message as soon as possible. This will allow us to have real-time access to our home. If there are elderly or children at home, it is particularly recommended to use smart door sensors because they can also monitor whether the elderly or children are going out, which can prevent them from getting lost.
In this article, we will explore which smart door sensors are the best on the market in 2024. Let’s analyze the functions, advantages, and disadvantages of these door sensors together. After reading this article, you will easily choose your favorite door sensor.
What is a smart door sensor and how does it work?
Smart door sensor is a safety device for house entry and exit alarm. Through the smart door sensor, users can know the opening and closing status of their own doors. It consists of sensors and magnets. When a door or window is opened, the magnet will separate from the sensor, and the sensor will transmit information to the communication module and send the information to the gateway. The gateway will then transmit the information to the mobile phone or cause relevant smart home devices to issue a warning.
how does a smart door sensor work
The core component of the smart door sensor is the reed switch. A reed switch is a device made of soft magnetic material, with two contacts sealed inside a glass tube and filled with inert gas to prevent contact oxidation. When the door or window is closed, the magnet approaches the reed switch, the two contacts are attracted, and the circuit is connected; When the door or window is opened, the magnet moves away from the reed switch, and the two contacts return to their original position under the action of elastic force, causing the circuit to disconnect. Sensors detect this magnetic change to determine the opening and closing status of doors or windows, and transmit this information to smart home systems or users.
Main features of smart door sensors
Different smart door sensors have different characteristics. When purchasing, it is important to first understand the features of smart door sensors, which is beneficial for buying a door sensor that is suitable for oneself. Let’s discuss the main features of door sensors separately below.
Connectivity
Door sensors are an important smart home device, and different door sensors support different communication protocols:
Wi-Fi: Wi-Fi smart door sensors can directly connect to your phone or other smart home devices without the need for an additional hub. This feature makes WiFi door sensors very suitable for small homes. WiFi door sensors can be directly connected to other smart home devices without the Internet, which can save money on hubs. However, WiFi door sensors consume more power compared to other alternatives, which is an important factor restricting the development of WiFi door sensors.
ZigBee or Z-Wave: The connection between Zigbee door sensors and other electrical devices requires a hub for relay. Zigbee door sensors can transmit information to farther places and can be used in large houses. ZigBee door sensors have low power consumption and can work continuously for longer periods of time. The disadvantage of ZigBee door sensors is that they require a hub to transmit signals to other smart devices and mobile phones during use.
Bluetooth: The power consumption of Bluetooth smart door sensors is the lowest and most energy-efficient. The transmission distance of Bluetooth is very close. If users need Bluetooth door sensors to transmit information to distant places, they need to add a Bluetooth gateway near the Bluetooth door sensor. Due to the need for an additional Bluetooth gateway, this will increase the cost of Bluetooth door sensors.
Alarm and Notification
Alarm and notification are the most important functions of smart door sensors. Smart door sensors are suitable for transmitting information to users in a timely manner when the door is opened. Some smart door sensors are connected to the smart alarm at home, and when the door is illegally opened, they will emit a buzzing sound in a timely manner. Some smart door sensors come with their own alarm.
In addition, some smart door sensors can be integrated with devices such as Amazon Alexa or Google Home, ensuring that smart door sensors can perform better.
Battery Life
Battery life is an important indicator of smart door sensors. If the battery life is long, users can reduce the frequency of battery replacement and maintenance. If the battery life is short, the frequency of battery replacement will increase. Under normal circumstances, the battery life of smart door sensors is usually between 6 months and 2 years. WiFi door sensors have higher power consumption and shorter battery life, while Zigbee and Bluetooth sensors have lower power consumption and longer battery life.
Nowadays, many smart door sensors have low battery warning, and users should replace the battery in a timely manner when receiving the low battery warning.
Smart Home Integration
Smart door sensors need to be matched with other smart home devices, especially the smart home hubs of large companies such as Amazon Alexa, Google Home, and Apple HomeKit, in order to perform better. Matching these hubs can make the door sensor better connected to the Internet.
Price and Value
Price is an important indicator that affects the sales of smart door sensors, and every user has a price expectation when purchasing a suitable door sensor. It is best to choose a smart door sensor that meets your needs at a relatively low price when purchasing. If there is no value management, we will purchase more expensive door sensors under the influence of the merchant.
