This two-channel relay module can control many appliances and other devices with high current. It is perfect for using Wi-Fi to regulate higher voltages in your project. It can regulate a wide range of appliances and other high-current devices. A microcontroller (Arduino, 8051, AVR, PIC, DSP, ARM, MSP430, or TTL logic) can directly control it using 3.3V or 5V logic signals.
