Opis
ESP8266 ESP-01 WiFi 5V 1x Rele
Brezžični nadzor preko WiFi omrežja
This WiFi relay module with ESP8266 ESP-01 provides a simple way to connect any electrical consumer (e.g., lights, fans, sockets, chargers) to a smart home system or DIY automation project. It integrates an ESP-01 WiFi module, an STM8S microcontroller for local logic, and a 5V relay with isolated COM/NO/NC contacts. It is designed for beginners, students, and advanced hobbyists, enabling quick WiFi control implementation without the need for custom power supply or protection circuit designs.
The module is powered by 5V DC via IN+/IN- terminals and connects to a WiFi network using a dedicated mobile application. The STM8S handles the underlying control of the ESP-01, LED indicators, and operating modes, simplifying the user experience by abstracting low-level WiFi initialization. UART (TX/RX) pins are available for advanced users to reprogram the ESP-01 or integrate it into custom systems.
Two push buttons (S1 and S2) allow for mode selection and factory reset, while LED indicators provide clear feedback on connection status and operating mode, aiding in troubleshooting. Typical use cases include remote switching of lights, fans, pumps, or small motors, controlling heating systems, creating simple WiFi switches, and integrating into other DIY controllers like Arduino, ESP32, or Raspberry Pi as a WiFi-controlled relay output..

Inženirski “PRO” nasvet
For optimal performance and reliability, ensure that the 5V power supply is sufficiently robust and stable. Crucially, establish a common ground (GND) connection across the power supply, the ESP-01 module, and any other connected electronics. When programming the ESP-01 via a USB-TTL adapter, position the jumpers to the upper setting during testing to prevent potential interference from the STM8S microcontroller. If controlling 230V mains voltage, strictly adhere to safety regulations regarding clearance distances and insulation. Consider using additional enclosures or fuses for enhanced safety.
