Description:
Transform your Raspberry Pi into a powerful smart home controller with the Waveshare 3-Channel Relay HAT. Designed for seamless integration with Raspberry Pi 3 and compatible models, this HAT allows you to create a DIY mobile-controlled system to switch up to three high-voltage electrical devices on or off directly from a smartphone application.
Each relay supports up to 230V AC at 5A, making it ideal for automating common household appliances such as lights, fans, or kitchen devices. Whether you're building a remote-controlled smart home setup, automating your workspace, or experimenting with IoT applications, this HAT provides reliable performance and easy installation.
With this expansion board, you can make your everyday appliances intelligent and remotely accessible, enabling real-time control, scheduling, and energy-saving solutions right from your Raspberry Pi.
