Description

The SN-3002-ZS-N01 is an industrial-grade acoustic sensor designed for continuous environmental and machinery noise monitoring. It employs a precision condenser microphone element paired with integrated signal conditioning circuitry to deliver accurate, real-time sound pressure level (SPL) data. The sensor’s robust ABS housing provides environmental protection and facilitates clean wall mounting in diverse settings.

Communication is handled via a standard RS485 interface, supporting the Modbus RTU protocol for reliable integration into distributed monitoring networks, Building Management Systems (BMS), and industrial PLCs. With a fast response time of ≤200 ms and a low operating current, it is engineered for 24/7 operation in applications ranging from smart office compliance to factory floor condition monitoring.

Key Features

  • Professional-grade condenser microphone with high signal-to-noise ratio.
  • RS485 Modbus RTU output for robust, noise-immune data transmission over long cable runs.
  • Wide operating voltage (10–30V DC) ensures compatibility with common industrial power supplies.
  • Durable ABS plastic housing ("King Shell") designed for wall-mount installation.
  • Low power consumption (≤50 mA) suitable for always-on monitoring systems.
  • Fast dynamic response (≤200 ms) captures transient noise events effectively.
  • Strong linearity and stable output across the entire 30–120 dB measurement range.
  • Plug-and-play configuration with standard 2-wire RS485 wiring for simplified setup.

Applications

  • Industrial machinery noise monitoring and predictive maintenance on factory floors.
  • Environmental noise compliance monitoring for offices, construction sites, and residential areas.
  • Building Automation Systems (BAS) and HVAC noise level control in smart buildings.
  • Workplace safety and occupational health sound level assessments.
  • Data center and server room acoustic environment monitoring.

Frequently Asked Questions

What is the communication protocol for the SN-3002-ZS-N01 noise sensor?

The sensor uses a standard RS485 serial interface and communicates via the Modbus RTU protocol. This allows for reliable, noise-immune data transmission over distances up to 1200 meters when using appropriate cable, enabling easy integration with PLCs, SCADA systems, and data loggers that support Modbus.

What power supply is required for this sound level sensor?

The sensor operates on a wide-range DC power supply from 10 to 30 volts. A typical 12V or 24V DC industrial power supply is perfectly suitable. It draws a maximum operating current of 50 mA, making it compatible with most centralized power systems used in automation and monitoring installations.

How do I mount and install the SN-3002-ZS-N01 sensor?

The sensor is designed for wall mounting using the included screws. Its "King Shell" ABS housing has integrated mounting points. For optimal performance, install it in the area of interest at a height representative of the sound field, avoiding direct contact with vibrating surfaces and ensuring the microphone grille is unobstructed.

What is the accuracy and response time of this noise sensor?

The sensor utilizes a high-sensitivity condenser microphone for precise readings across its 30 dB to 120 dB range. It features a fast response time of ≤200 milliseconds, allowing it to accurately capture transient noise events and provide real-time sound level data for monitoring and control applications.
