Features
Probe-Style/Tube Design
Features a tubular housing made of stainless steel or high-density polymer, offering a compact structure that facilitates easy installation via threaded connections or mounting brackets.
Weather Resistance and Compact Design
The housing provides excellent protection against rain and snow, withstanding harsh weather conditions. Its small, lightweight form enables rapid installation in diverse challenging outdoor environments.
High-Precision Digital Output
Incorporates a high-sensitivity condenser microphone and a digital signal processing (DSP) chip with A-weighted (simulating human ear perception) frequency processing, typically achieving measurement accuracy of ±0.5 dB.
RS485 Communication Interface
Utilizes the standard Modbus-RTU protocol. Compared to analog signals (e.g., 4-20mA), digital output offers superior interference resistance, supports multi-point networking, and enables transmission distances exceeding 1000 meters.
Wide-range measurement
Typically covers 30 dB (quiet environments) to 130 dB (industrial high noise), with a broad frequency response span (e.g., 20 Hz to 12.5 kHz).
All-weather monitoring
Typically equipped with an anemometer cup/rain cover to effectively reduce wind noise interference and protect internal sensor components from moisture damage.
Application

Smart Cities and Environmental Monitoring
Installed on streetlight poles or at traffic intersections to monitor urban environmental noise pollution in real time.

Industrial Parks and Factories
Monitor operational noise in workshops, machine rooms, and large equipment (such as air compressors and cooling towers) to prevent noise violations or enable equipment failure early warning.

Construction Sites
Meet environmental protection agencies’ requirements for decibel monitoring at construction sites and trigger alarms when levels exceed standards.

Traffic Monitoring
Deployed near highways, railways, or airports to assess transportation impacts on surrounding residential areas.
