Overview

Waterproof, wall-mounted noise sensor features a sealed silicone foam strip structure and a waterproof, breathable membrane design, providing excellent waterproof and dustproof performance. SUCH noise sensor can operate stably in environments ranging from -20℃ to 60℃. The sensor supports 5-12V DC power supply with an operating current of approximately 20mA. It has a serial TTL communication interface, compatible with active, passive, and Modbus RTU communication modes. Its resolution reaches 0.1dB, with a response time of only 300ms. The baud rate can be flexibly set via configuration software (supporting 9600-115200bps). Externally, it uses a 4-pin aviation socket design for easy installation and is widely applicable to environmental monitoring, smart cities, industrial noise detection, and other scenarios.

FAQ

Q1: What environments is the waterproof noise sensor suitable for? ❯

The sensor is designed for both indoor and outdoor environments, including industrial sites, urban areas, and locations exposed to rain or high humidity.

Q2: Can the sensor be submerged in water? ❯

No. The sensor is waterproof and weather-resistant, but it is not designed for long-term underwater use. It can withstand rain and splashes without affecting performance.

Q3: Does the waterproof design affect sound measurement accuracy? ❯

No. The sensor uses a waterproof, sound-permeable membrane that ensures accurate sound detection while protecting internal components from moisture.

Perfect for Outdoor Installation

One of the reasons I chose this sensor was the waterproof feature, and it definitely delivers. We mounted it outdoors to monitor environmental noise, and it’s handled wind and rain without any issues. Detection is sensitive and consistent. Very happy with the purchase.
