Someone said, give me a relay I can change the world. Yes this is a joke, but a relay can really be used to make a lot of things. Through a relay, you can control all of the electrical appliances at home, lights, water heaters, doors, almost everything.
Here we introduce an interesting relay module, Heelight Relay. Heelight Relay is a multitalented, stand-alone relay module with microcontroller based on STM32. And the most important is you don't need to programming at all.
We can control the relay through a sound command. We offer an App to make the sound commands. With a set sound command, the relay on the module can be opened or closed. Heelight Relay can set different voice commands, you don't need to programm the board, just press the button is enough. The sound command is valid in the range of 10 meters, which allow you to open the lamp when you are out of the door.
What are you waiting for, join us to change the world with sound!
