WiFi smart switch
With the vigorous development of the Internet of Things, smart home has become a high-profile emerging field, more and more smart products have entered the consumer market and have been favored by the majority of users, and the traditional mechanical switches used to control the state of equipment are also facing intelligent upgrades.
A variety of smart switches have appeared on the market to respond to a variety of scenarios and needs. Espressif's smart switch solution is based on the ESP8266EX and an upgraded version of the ESP32-C3 chip, which allows users to upgrade the traditional mechanical single live wire switch to an intelligent single live wire switch without changing the wiring or configuring the gateway, building a safe and reliable smart switch with low power consumption, excellent Wi-Fi performance, and no need to configure a gateway.
Program features:
1. Ultra-low power consumption
In order to avoid abnormal flickering of the lamps in the circuit, it is especially important to control the power consumption of the Wi-Fi single live wire switch. The chip uses advanced power management technology and superior Wi-Fi processing strategy, so that the switchgear can maintain Wi-Fi connectivity while also having ultra-low power consumption, which meets the needs of most lighting scenarios.
Second, the wifi performance is excellent:
Since smart switches need to be embedded in the wall when installed, the device's Wi-Fi penetration immunity through the wall also needs to meet a higher standard. The chip delivers industry-leading RF performance for smooth, stable Wi-Fi connectivity even when the device is mounted inside a wall. When ESP32-C3 uses Wi-Fi for communication, compared with ESP8266EX with a maximum communication distance of 250 300 m, ESP32-C3 can reach a maximum communication distance of 500 m in an open environment, and can still reach 20 m when crossing three walls, fully meeting the communication needs of daily home scenarios. In addition, the ESP32-C3 has good compatibility and flexibility. Users can also freely configure Wi-Fi parameters according to network conditions to cope with various complex environments.
3. Safety and reliability
ESP32-C3 has a complete security mechanism, supporting secure boot based on RSA-3072 algorithm and Flash encryption based on AES-128-XTS algorithm to ensure that the switchgear firmware is secure, and only user-specified programs are run. The hardware accelerator of the chip supports a variety of encryption and decryption algorithms, and also ensures that the switch securely transmits data on the local network and the cloud to prevent all kinds of malicious attacks.
