Noise Detection Sensor with High Sensitivity Microphone

High-quality noise sensor uses the ModBus-RTU communication protocol, supports RS485, 4-20mA current and 0–5V voltage output, operates within a 10-30VDC voltage range, and consumes only 0.1W. SUCH sensor features a measurement range of 30-130dB and a frequency response of 20Hz–12.5kHz, with a resolution of 0.1dB. At 94dB@1kHz, its measurement accuracy reaches ±0.5dB, with a response time ≤3s and long-term stability better than 2%. The sensor supports three baud rates: 2400, 4800 (default), and 9600bps. It offers reliable communication and stable performance, making it suitable for environmental noise monitoring, industrial noise detection, and intelligent control applications.
