Do smart locks need WiFi?
A smart lock needs to be able to communicate with the rest of your smart home setup and with your phone. Most will do that using one of three common communication protocols: Bluetooth, Z-Wave or Wi-Fi.
According to the survey data, since 2008, China's smart lock industry has entered a period of growth, and smart lock enterprises have mushroomed.The total output value of the smart lock industry has reached 10 billion yuan, and smart lock has ushered in its golden age.
What type of lock can be called a smart lock? It uses electromagnet and lock as executive unit, combine electronic technology and integrated circuit design components with a variety of innovative identification technologies (including computer network technology, built-in software cards, network alarms, lock body mechanical design) and other comprehensive products. Compared with the traditional mechanical lock, there is no need to use a metal key, so it is convenient to use, and the confidentiality is extremely strong.
How does a smart lock work? It is based on 51 series single chip computers, with corresponding hardware circuit, complete password setting, storage, identification and display, drive the electromagnetic actuator, detect its driving current value, receive the alarm signal sent by the sensor, send data and other functions. The microcontroller receives the entered code and compares it with the password stored in the EEPROM. If the password is correct, the electromagnetic actuator is unlocked; if the password is incorrect, the operator is allowed to re-enter the password, which can be entered up to three times; if the three times are not correct, the microcontroller alerts the intelligent monitor through the communication line. The single chip microcomputer will send the driver current value of the electromagnetic actuator to the intelligent monitor and send the alarm information from the sensor interface to the intelligent monitor as the basis of intelligence analysis.
