Heelight Relay is uniquely designed to control a relay using digital sound commands over a distance of about 10 meters. It is built with the Heelight Core (https://longan-labs.cc/heelight-core/), a smart sound sensor that can recognize up to 500+ digital sound commands.
Simply, you can now turn on and off lamps, fans, solenoids, and other small appliances that run on up to 220VAC or DC power by playing a sound with your smartphone, computer, or any audio player.
The Heelight Relay is integrated with an STM32 Arm Cortex microcontroller, pre-programmed for digital sound recognition during the manufacturing of this module hence doesn't require any further programming to process the digital sound commands. The module can be configured to response for a digital sound command using the built-in two momentary push buttons.
Anyone can set up the Heelight relay in no time to control an appliance with digital sound commands!
Each Heelight relay module comes with a fully assembled and tested PCB.
Note: 5V DC switching power supply is not included with this package.
