IoT service applications based on scene linkage, such as smart bulbs embedded with wireless WiFi modules, smart plant growth machines, wireless temperature and humidity sensing devices, smart sweepers, and smart central control panels.

More and more smart products are entering ordinary homes to provide users with various smart experiences and services.

Wi-Fi technology is a wireless technology with the advantages of fast transmission speed and no wiring. In recent years, with the rise of the concept of the Internet of Things, people's lives are more and more closely related to the Internet.

With its prominent features, Wi-Fi technology can easily and conveniently connect to the Internet through a Wi-Fi module, becoming many smart small appliances.

The Lexin ESP32 feature-rich Wi-Fi & Bluetooth MCU is suitable for various IoT applications. The performance is stable and the operating temperature range is -40°C to +125°C. Integrated automatic calibration circuit realizes dynamic voltage regulation, eliminates external circuit defects, and adapts to changes in external conditions.

ESP32 integrates functions such as antenna switch, RFbalun, AS321KTR-E1 power amplifier, receiving low noise amplifier, filter, and power management module. ESP32 can achieve powerful processing performance, reliable security performance and Wi-Fi & Bluetooth capabilities.

Feirui Technology Lexin Agent is committed to providing safe, stable and energy-saving Lexin AIOT solutions to help create a smart world where everything is connected.

Designers can meet their own development needs, simply and quickly assemble and develop their own products. After successful networking, the main control chip receives the signal sent by the mobile APP through the Wi-Fi module, controls household appliances and household appliances according to the protocol signal, and feeds back the running status and parameters in real time.

The mobile application sends parameters or control information through the Wi-Fi module and transmits it to the main control chip according to the protocol. The main control chip judges and responds according to the data. At the same time, the main control chip returns the status and parameters of the device to the mobile application to achieve the purpose of intelligent interaction.

The ESP32 can run applications or host MCU's Wi-Fi and Bluetooth capabilities as a standalone system via SPI/SDIO or I2C/UART interfaces.

The mobile phone operates the smart terminal through the corresponding application program. The smart terminal is connected to the wireless router through the WiFi module, and is connected to the remote cloud server through 2G, 3G, 4G and 5G wireless interfaces or wired broadband interfaces.

With the gradual popularization of IoT devices, users have higher requirements on the standby time and response speed of the devices. For example, WiFi door magnets are usually matched with 1000mah nickel-metal hydride batteries to ensure at least one year of standby time; low-power smart WiFi door locks should also ensure a certain continuous working time.

ESP32 series modules integrate Wi-Fi, traditional Bluetooth and Bluetooth low energy functions. Considering the high power consumption of the user in the actual operating frequency and the wake-up state, the power consumption of the device needs to be further optimized to meet the expected battery life of one year and avoid frequent battery replacement.

For some wireless terminal devices equipped with coin-cell lithium batteries, the minimum operating voltage of the Soc platform needs to be supported to 2.3V. The nominal voltage of lithium batteries is generally 3.0V. With the gradual discharge of the battery, when the voltage reaches 2.3V, the device can still work normally to prolong the working life of the battery as much as possible.

In order to ensure the service life of wireless smart devices, when the smart module is integrated into the product, a series of aging and stability tests are required, such as surface anti-static level test, high temperature stability test, low temperature startup test and high and low temperature cycle test. The specific test model can be adjusted appropriately according to the specific equipment type.

With the in-depth development of the AIOT industry, the application of IoT wireless modules has become more and more extensive, and more and more intelligent networking devices integrating wireless modules have entered thousands of households.
