Opis
ESP8266 ESP-01 WiFi 12V 1x Rele
Brezžični nadzor preko WiFi omrežja
The ESP8266 ESP-01 WiFi 12V 1x Relay module provides a straightforward method to integrate any consumer device (lights, fans, sockets, chargers) into a smart home or DIY automation project. It combines an ESP-01 WiFi module, an STM8S microcontroller for local logic, and a 12V relay with isolated COM/NO/NC contacts on a single board. The STM8S microcontroller manages the ESP-01, LED indicators, and operating modes, allowing users to focus on application rather than low-level WiFi module initialization.
UART (TX/RX) pins are available for reprogramming the ESP-01 or integrating it into custom systems. The module is suitable for beginners, students, and advanced hobbyists looking to quickly implement WiFi control without designing power supply and protection circuits. Power is supplied via IN+/IN- terminals, and the load is connected to the relay terminals.
The module connects to a WiFi network using a dedicated mobile application. Use cases include remote switching of lights or LED strips, controlling fans, pumps, or small motors, managing heating systems, creating simple WiFi switches for workshops or garages, and integrating into DIY controllers (Arduino, ESP32, Raspberry Pi) as a WiFi-controlled relay output. The module is compatible with most existing ESP-01 firmware solutions and typical mobile applications for WiFi switches using TCP communication.
The ESP-01 can be reprogrammed with custom firmware (e.g., ESP-Easy, Tasmota, custom Arduino sketch) via UART..

Inženirski “PRO” nasvet
For WiFi relay modules like this, power supply and grounding are critical. Ensure the 12V power source is sufficiently powerful and reliable, and crucially, that the GND is common between the power supply, ESP-01, and other electronics. If using a USB-TTL adapter for ESP-01 programming, move the jumpers to the upper position during testing to avoid interference from the STM8S. When controlling 230V mains voltage, always observe safety distances, ensure proper insulation, and use additional enclosures or fuses if necessary.
