The ESP8266 WiFi 1-Channel Relay Module is a compact, WiFi-enabled switching board built around the popular ESP8266 chip. It lets you turn a single device or circuit on and off remotely over your wireless network, making it a favorite building block for smart irrigation controllers, home-automation projects, and DIY electronics. It suits hobbyists, makers, students, and anyone automating a pump, valve, light, or appliance from a phone or a custom app.
Key features
- Based on the widely supported ESP8266 WiFi microcontroller for wireless control.
- Single relay channel to switch one load on or off.
- Controllable over WiFi from a phone, browser, or your own application.
- Compatible with common maker platforms and firmware found in the ESP8266 community.
- Compact board that fits neatly into project boxes and automation setups.
Typical uses
- Remote on/off control of a small water pump or solenoid valve in a smart irrigation system.
- WiFi switching of lights, fans, or appliances in home-automation builds.
- Greenhouse and hydroponics automation projects.
- Learning and prototyping IoT control circuits.
How to choose / tips
- Confirm the relay's rating matches the load you plan to switch before wiring.
- Use a stable, properly rated power supply for reliable WiFi operation.
- If you need to control more than one device, plan for a multi-channel module instead.
- Flash firmware that fits your project, whether ready-made or custom-coded.
