Indoor noise online monitoring instrument for postpartum center and health care baseIt is a professional acoustic monitoring device developed based on advanced sensor technology and intelligent algorithms. Its exterior design is simple and compact, easy to install in any corner of the room, does not occupy too much space, and will not damage the overall interior decoration style.
Indoor noise online monitoring instrument for postpartum center and health care baseBuilt in high-precision sound pressure sensor, capable of real-time collection of indoor noise data, accurately capturing subtle sound changes as low as 1 decibel. By using built-in intelligent chips and professional algorithms, the collected data can be quickly analyzed and processed. At the same time, the device supports multiple data transmission methods, such as Wi Fi, 4G, etc., and can upload monitoring data in real time to cloud platforms or user terminal devices, making it convenient for users to view indoor noise conditions anytime and anywhere. In addition, parameter settings, historical data queries, and analysis can be performed on the device through an app or web platform.
Product Features
High precision monitoring: using sound pressure sensors, the monitoring accuracy can reach ± 0.5 decibels, ensuring accurate and reliable data, and providing users with real indoor noise conditions.
Real time dynamic monitoring: Real time monitoring data is updated at a second level frequency, reflecting the instantaneous changes in indoor noise in a timely manner, allowing users to grasp the noise dynamics in real-time.
Intelligent alarm function: supports custom noise threshold. When indoor noise exceeds the preset threshold, the device immediately issues an alarm through various methods such as sound and light alarm, APP push, etc., reminding users to take noise reduction measures.
Data visualization analysis: Provide rich data visualization charts, such as line charts, bar charts, pie charts, etc., to visually display the trend of noise intensity over time, the distribution of noise in different time periods, etc., helping users to deeply analyze the sources and patterns of noise.
Low power consumption and long battery life: adopting energy-saving design and large capacity lithium battery, it can work continuously for up to 72 hours on a single charge, and supports external power supply to ensure stable operation of the device.

Product features
real-time monitoring
Real time monitoring of environmental noise levels, providing accurate noise data through high-precision sensors and advanced data processing technology.
Data display and storage
The detector is equipped with a liquid crystal display screen, which can intuitively display the current noise level, peak data, historical data, etc. At the same time, the detector has data storage function, which can record long-term noise data and support data export to a computer for further analysis.
Over limit alarm
When the monitored noise data exceeds the set threshold, the device automatically alarms and uploads it to the regulatory platform,
Timely notify relevant personnel to take corresponding measures to effectively prevent the occurrence of noise pollution exceeding the standard.
remote access
Support wireless 4G/5G, Bluetooth and other communication methods to achieve real-time data transmission and remote access. Users can remotely view and manage monitoring data through terminal devices such as mobile phones and computers.
Multiple weighting methods
By using high-precision sensors and multiple weighting methods (such as A, C, Z weighting), it can meet the requirements of different noise measurement standards and provide accurate noise measurement results.
