Outdoor Noise Sensor

Outdoor Noise Sensor - High-Precision Environmental Noise Monitoring 

Product Introduction  

Our outdoor noise sensor is a professional, high-performance device designed for precise measurement of environmental sound. It meets the IEC 61672 Type 2 standard, is durable and suitable for long-term outdoor use. The sensor employs a high-performance capacitive microphone and internationally recognized frequency-weighting technology, enabling accurate detection of noise levels from 30 to 130 decibels, meeting diverse monitoring needs. Its IP65 protection grade ensures reliable operation in harsh weather conditions with minimal maintenance requirements. It is ideal for urban noise monitoring, smart traffic, construction site regulation, industrial park environmental assessment, and more.

Technical Specifications of Outdoor Noise Sensor  

 Working Principle of Outdoor Noise Monitoring Sensor  

The outdoor noise sensor captures environmental sound signals using a high-sensitivity capacitive microphone and converts them into electrical signals. These signals are processed internally and combined with frequency weighting (in compliance with IEC 61672 Type 2 standard), simulating the human ear's perception of different frequency sounds to provide precise noise level data. The fast response time (200 ms) ensures real-time capture of dynamic noise changes. The sensor supports RS485 output, which can be easily integrated with data acquisition systems, providing stable and reliable data for long-term monitoring.

Designed for Outdoor Use  

This noise sensor is specifically built for outdoor environments with the following features:  

- Strong Weather Resistance: IP65 protection grade, dust and water-resistant, adaptable to rain, snow, extreme temperatures, and other harsh conditions.  

- Long-Term Stability: Robust housing and low power design (20 mW) ensure reliable operation for several years.  

- Easy Integration: RS485 output and standard MODBUS protocol make it easy to integrate into environmental monitoring or smart management systems.  

- Minimal Maintenance: After calibration, it can be used for extended periods with only occasional cleaning of the microphone to maintain accuracy.
