Wi-Fi Communication Board for Smart Home Outlet

Product Specifications

Technical details and manufacturing context for Wi-Fi Communication Board

Definition

The Wi-Fi Communication Board is an electronic component used in the Smart Home Electrical Outlet with USB Charging. It provides the hardware and firmware necessary for the outlet to connect to a local Wi-Fi network, enabling remote control, scheduling, energy monitoring, and integration with smart home ecosystems via mobile applications or voice assistants. The board is designed for industrial-grade operation and is intended for integration into the outlet's enclosure. It operates on a 2.4 GHz Wi-Fi network using IEEE 802.11 b/g/n protocols. The board includes a Wi-Fi module with an integrated microcontroller and radio transceiver, along with supporting circuitry. It communicates with the outlet's power switching and USB charging circuits via UART, SPI, or I2C interfaces. The board is powered by a 3.3–5 V DC supply and is rated for operating temperatures from -40 to 85 °C, with non-condensing humidity from 5 to 95 % RH. It supports data rates from 1 to 150 Mbps (802.11n HT20), transmit power of 18–20 dBm, and receive sensitivity of -98 to -90 dBm. The board features a PCB antenna with 2–3 dBi gain. Typical board dimensions are 25×18 mm, and weight is 3–5 g. The ingress protection rating depends on the enclosure and ranges from IP40 to IP65. All values are reference ranges and must be verified with the legal manufacturer or supplier for the specific model and application. The board is not certified to any specific standard; any listed standards are for procurement reference only.

Working Principle

The board contains a Wi-Fi module (e.g., ESP8266, ESP32) with an integrated microcontroller and radio transceiver. It connects to a 2.4 GHz Wi-Fi network using standard protocols (IEEE 802.11 b/g/n). The microcontroller runs firmware that manages the network connection, receives commands from a cloud server or local network, and translates them into control signals for the outlet's power switching and USB charging circuits via a communication bus (e.g., UART, SPI). The board's antenna transmits and receives RF signals, enabling wireless communication. The firmware handles network protocols, data encryption, and command interpretation. The board's power supply regulates voltage for the logic and RF circuitry. The operating temperature and humidity ranges define the environmental limits for reliable operation. The board's interfaces allow integration with the host outlet's microcontroller. The board's performance parameters, such as data rate and transmit power, determine the wireless link quality. The board's dimensions and weight are typical for the module and may vary with the specific implementation.

Frequently Asked Questions

What is the operating temperature range of the Wi-Fi Communication Board?

The board is rated for an operating temperature range of -40 to 85 °C. This is an industrial-grade range, and exceeding these limits may cause failure. Always verify the actual limits for your specific model and application with the manufacturer.

Which Wi-Fi standards does the board support?

The board supports IEEE 802.11 b/g/n protocols on the 2.4 GHz ISM band. It supports data rates from 1 to 150 Mbps (802.11n HT20). These are reference values; confirm the exact capabilities with the supplier.

How does the board communicate with the host outlet?

The board communicates with the host outlet's power switching and USB charging circuits via a communication bus such as UART, SPI, or I2C. The specific interface used depends on the integration design and must be verified with the manufacturer.

What is the ingress protection rating of the board?

The board itself does not have an ingress protection rating; the rating depends on the enclosure in which it is installed. The overall product may achieve IP40 to IP65, but this must be confirmed for the specific enclosure and application.
