Key Features of ESP8266 01 + 5V WiFi Relay Module
- WiFi-Enabled Relay Control: Toggle the relay on/off remotely over a local WiFi network or the internet using the ESP8266-01's built-in WiFi capabilities.
- Plug-and-Play Combo: The relay module features a dedicated ESP-01 socket - simply plug in the ESP8266-01 and power with 5V to get started.
- Onboard Voltage Regulator: Built-in 3.3V regulator on the relay board powers the ESP8266-01 directly from the 5V supply, eliminating the need for separate level conversion.
- High-Current Switching: The relay handles up to 10A at 250V AC, suitable for controlling household appliances, solenoid valves, motors, and lighting.
- SPDT Relay Output: Normally Open (NO), Normally Closed (NC), and Common (COM) terminals provide flexible wiring for both on-state and off-state default configurations.
- Arduino IDE Compatible: Program the ESP8266-01 using the familiar Arduino IDE with the ESP8266 board package - extensive libraries and community examples available.
- Compact Form Factor: The small footprint makes it easy to embed inside electrical enclosures, switchboards, or custom housings.
- Optocoupler Isolation: Relay driver circuit includes optocoupler isolation to protect the ESP8266 from relay switching noise and back-EMF.
- Status Indicators: Onboard LEDs show power status and relay state at a glance for easy debugging and monitoring.
- OTA Update Capable: With appropriate firmware, supports over-the-air updates so you can reprogram without physical access.
- Ideal balance of cost, size, and functionality for wireless relay control
