Frequently Asked Questions

What type of voice does this sensor recognize?

This sensor is specifically designed for digital voice recognition, meaning it decodes pre-programmed digital sound wave patterns or commands. It does not recognize or process natural human speech. For human voice recognition, a different module like a speech recognizer is required.

How do I communicate with the Grove Heelight Sensor?

The module communicates via a TTL-level serial UART interface. You must connect its TX/RX pins to a microcontroller's serial port and configure communication at 115200 baud. It will output digital codes corresponding to recognized commands, which your code can then interpret and act upon.

What is the operating voltage and power requirement?

The sensor operates from a 3.3V to 5V DC power supply, making it compatible with most common microcontroller logic levels. It draws approximately 15 mA during operation, ensuring low power consumption for battery-powered or energy-sensitive projects.
