The rapid development of the Internet of Things technology gives home locks an intelligent life. Smart door locks are a popular product in smart homes. It truly realizes the high-tech living experience of "keyless entry" and "remote authorized access".

Now the low-power WiFi Module manufacturer SKYLAB will take you to understand the WiFi smart door lock solution.

Smart door lock solution WiFi module introduction

WG219 is a low-power WiFi module developed by SKYLAB for IoT smart home and smart industries. Based on the ESP8266 solution, this WiFi module provides UART serial port. Compatible with 802.11b/g/n wireless standard protocol, support multiple cloud platform docking, etc. Support UART-WiFi-Ethernet data transmission. Using WG219, you can develop IoT WiFi solutions safely, stably, simply and quickly, and shorten the development cycle of WiFi products.

How is the low-power WiFi smart door lock solution realized?

The low-power WiFi module WG219 is built in the smart door lock. The user downloads the relevant APP on the mobile phone, and within the WiFi signal coverage of the router, can connect to the WiFi through the router to establish a connection with the WiFi module in the smart door lock. The mobile phone reads the smart door lock information and tries to pair it. And send the unlock request to the server.

The server sends the unlock instruction to the mobile phone, the mobile phone receives the instruction, and then sends the instruction to the smart door lock through WiFi for unlocking. In locations that cannot be covered by the WiFi signal of the router, you can also access the cloud through 3G/4G/5G signals to achieve smart door lock control.

(1)WiFi module smart door lock solution description

The WiFi module in the smart door lock usually uses the serial port pins to connect with the serial port of the main control MCU. Works in transparent transmission mode. The main control MCU sends the control instructions and device status related to the smart door lock to the WiFi module through serial data packets.

After the WiFi module is configured, the data is transmitted to the cloud platform of the smart home system. The mobile APP terminal is based on the device status data on the cloud platform to realize control interaction.

(2)Advantages of WiFi module smart door lock solution

Add a low-power WiFi module to the existing traditional door lock. The door lock can be unlocked and controlled through a smartphone. No need for cumbersome key cards and keys, more intelligent and convenient.

In conclusion

Smart door locks have gone through the development of traditional mechanical door locks to electronic door locks and then to smart door Door locks have gone through the process of mechanical door locks to electronic door locks, and then to smart door locks. Smart door locks are more intelligent and simplified in terms of user identification, security, and management.
