Outdoor Noise Sensor, 30dB~130dB, RS485

Louvre box type outdoor noise sensor uses an RS485 interface and supports the MODBUS-RTU protocol. It offers a wide measurement range of 30dB to 130dB, a high resolution of 0.5dB, and a measurement accuracy of ±5% (A-weighted). SUCH noise sensor has a frequency response range of 10Hz to 20kHz and supports time-weighted F-mode, ensuring accurate and reliable data. Its shutter-style design allows for stable operation in environments ranging from -20℃ to 70℃ and 25% to 90% relative humidity. It is suitable for outdoor environmental monitoring (such as urban roads, industrial parks, and environmental monitoring), as well as indoor locations (such as warehouses, computer rooms, and factories).

Feature

• Industrial-grade Design: Built to meet industrial standards for continuous 24-hour fixed-point noise monitoring.
• Reliable Communication: Supports RS485 interface with MODBUS-RTU protocol; configurable address and baud rate (default 9600bps).
• High Accuracy: High integration and precision with minimal measurement error for stable, reliable data.
• Durable Construction: Compact 6-layer louvered enclosure made of UV-resistant materials, rain- and snow-proof, suitable for harsh environments.
