The ESP8266 WiFi Relay Module integrates a high-performance ESP8266 WiFi module with a microcontroller, enabling wireless control of relays through a mobile app within a local area network (LAN). This dual-channel relay module is specifically designed for controlling higher voltages, supporting up to 250V AC and 30V DC, making it ideal for various applications such as operating remote lights, managing appliances, and triggering systems based on signals from the ESP8266 module. Equipped with LED indicators that reflect the module's operational status, it features a red power activation LED that illuminates when a signal is received on the IN pin. Users will hear an audible click when the relay activates, connecting the output pins. The relay is controlled by the ESP8266 module, which requires initial configuration via UART commands. Once programmed and powered, the module operates independently, making it an excellent choice for Internet of Things (IoT) projects.

Features:

Name: ESP8266 ESP-01 12V 2 Channels WiFi Relay Module Home Remote Control Switch
SKU: 274707

Transmission Distance: In an open environment, the module supports a maximum stable transmission distance of 100 meters when the mobile phone is connected directly to the WiFi module. When both the WiFi module and mobile phone are connected to a router, the effective range depends on the router’s signal strength.

Smart Config Technology: Easily configure the WiFi account and password using the ESP-01 WiFi module through the mobile app, with the ability to remember the configured username and password even after power-off.

Relay Specifications: The module features a 12V, 10A relay capable of switching up to 250V AC and 30V DC, designed for over 100,000 activation cycles. It includes diode discharge protection and ensures a short response time.

Mode Selection and Indicators: The board has a mode selection feature and real-time working status indicators to provide feedback on operational conditions.

Debugging Interface: Reserved UART debug interface and STM8 SWIM programming download interface for development and troubleshooting.

Applications:

Home Automation: Control lights, fans, and appliances remotely through your smartphone.

Industrial Automation: Monitor and manage industrial equipment from a distance, improving operational efficiency.

Smart Lighting: Create automated lighting systems that can be controlled based on schedules or triggers.

Security Systems: Integrate with alarm systems for remote monitoring and control of security features.
