Data Harvest Sound Sensor 3175

The Data Harvest Sound Sensor 3175 is a versatile dual‑range sensor designed to accurately measure both sound pressure level (dBA) and sound waveform (mV). Developed to approximate the frequency range and sensitivity of the human ear, this sensor is ideal for a wide variety of classroom investigations involving sound, noise levels, and acoustic analysis.

Its high sensitivity and reliable performance make it suitable for use in physics, biology, and environmental science, whether measuring ambient noise, studying waveforms, or analysing sound sources.

Key Features
