SEN0232

SEN0232 is an Arduino compatible Gravity: analogue sound level meter (also known as decibel meter, noise meter). It uses instrument circuit and low noise microphone which enable it to accurately measure the sound level of the surrounding environment. It can be applied to environmental noise testing, such as highway noise monitoring station, bedroom noise monitoring, etc.

• High precision, use instrument circuit, low noise microphone
• Wide input voltage from 3.3 to 5.0V
• Simple conversion, linear analogue output
• No complex algorithm is required
• Easy to use, plug and play, without soldering
• Measuring range from 30dBA to 130dBA, measurement error of ±1.5dB
• 31.5Hz to 8.5kHz frequency response, 125ms time characteristics
• 22mA at 3.3V, 14mA at 5.0V input current
• 0.6V to 2.6V output voltage
• Module size is 60mm x 43mm / 2.37in x 1.68in
