DFRobot Gravity Analogue Sound Sensor for Arduino

The DFRobot Gravity Analogue Sound Sensor is a versatile and easy-to-use component designed for a wide range of Arduino-based audio detection projects. This sensor is specifically calibrated to detect ambient sound loudness, allowing your microcontroller to collect and respond to audio signals for interactive applications.

With a wide operating voltage range from 3.3V to 5V, it is compatible with most common microcontroller boards and development shields, including the DFRobot Arduino V7.1 IO Expansion Shield. The analogue interface provides a straightforward and reliable method for reading varying sound levels, enabling precise control in your projects.

Key Features & Applications

This sensor is perfect for creating interactive devices. One popular application is a 'clap and buzz' system to locate misplaced items like keys by triggering a buzzer upon detecting a specific sound. Its ability to measure sound intensity makes it suitable for noise-activated switches, sound level meters, and interactive art installations.

Build Quality & Specifications

Constructed with a high-quality connector and an immersion gold surface for excellent corrosion resistance and signal integrity, the sensor is built to last. The board features a clear, icon-based design to simply illustrate its function for easy integration. It includes a standard assembly structure with two 3mm mounting holes spaced at 5mm intervals for secure installation.

The compact board size of 22x30mm (0.87 x 1.26 inches) makes it ideal for projects where space is at a premium. The kit includes the analogue sound sensor board and a matching analogue cable, providing everything you need to get started quickly.
