Waterproof Noise Sensor, Sound Pressure Detection

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.
