If you need to control the AC power (lights, home equipment's), a thyristor is what you need. This is a very common thyristor module with very low on-resistance and a control voltage, that is compatible with any 3.3V or 5V micro-controller or mechanical switch. This allows you to control high-power devices with very low-power control mechanisms.
This board has an optoisolator to protect your micro-controller from high AC currents.
We also left more space, if you need to install the heat sink for thyristor.
