Good value, clear instructions needed

The sensor itself is excellent and picks up sound clearly. I wish the pinout diagram was printed on the back, but once wired correctly, it performs well.

Compact and efficient

Small footprint fits perfectly in my wearable prototype. Power consumption is low, which is crucial for battery-operated devices.

5 FAQ

Q: Does it come with headers soldered?

A: No, the module is shipped without headers to allow for flexible mounting options. You will need to solder your own pins or wires.

Q: What is the maximum operating voltage?

A: The module can safely operate between 2.7V and 5.5V. We recommend using 3.3V or 5V depending on your microcontroller logic level.

Q: Is the output digital or analog?

A: This module provides an analog output voltage that varies with sound intensity. You will need an ADC (like on an Arduino) to read the values.

Q: Can I use this outdoors?

A: The PCB is not weatherproof. If used outdoors, it must be housed in a protective enclosure that allows sound to pass through while blocking moisture.

Q: Can this module detect human speech specifically?

A: Yes, the frequency response covers the human voice range (approx. 300Hz-3400Hz), making it suitable for speech detection applications.
