Gravity: Analog Sound Sensor
This Analog Sound Sensor is compatible with Arduino, detects sound intensity, and features improved voltage range and interfaces. Suitable for DIY projects. Sound Sensor is typically used in detecting the loudness in ambient, the Arduino can collect its output signal and actuate accordingly. You may use it to make some funny interactive works such as a “Clap and Buzz” to find your lost keys.
Gravity: Digital Speaker Module
This speaker module features an 8002 amplifier IC, adjustable volume, digital interface, and compact design, suitable for Arduino projects with voltage range 2.0-5.5 Volt.
