DFRobot Gravity Sound Sensor

The Gravity Sound Sensor is used to detect the sound intensity of the environment. The DFRobot Sound Sensor is an analog sensor and only need a dedicated data line. The sensor can be extended with the Arduino board, in combination, it is very easy to achieve the sound perception associated with the interaction effect. Definition of the sound sensor pin: 1- Signal Output 2- GND 3- Power. Sound sensor interface socket for PH2.0. Extendable analog sensor; Detects the sound intensity; Power supply: 5VDC
