Hello fellow electric enthusiasts,

I hope this message finds you well. I am an engineer who is passionate about building innovative solutions, and currently, I'm embarking on a project to develop a noise monitoring sensor specifically designed for <Mod:clip>. I believe that such a sensor could greatly benefit both hosts and guests by ensuring a peaceful and comfortable environment for all.

While I have a solid background in engineering, I am reaching out to this knowledgeable community today to seek any advice, suggestions, or insights you may have regarding the development of this noise monitoring sensor. I would greatly appreciate your guidance in the following areas:

  1. Sensor Selection: I am exploring various sensor options for accurately measuring noise levels in different environments. If you have any recommendations for specific noise sensors or technologies that have proven to be effective, I would love to hear your thoughts.
  2. Connectivity and Integration: To make this sensor user-friendly and convenient, I envision integrating it with existing home automation systems or establishing wireless connectivity. If you have experience with similar projects or suggestions for seamless integration with , please share your insights.
  3. Power Efficiency: Considering that the sensor will be continuously monitoring noise levels, power efficiency is crucial. Any suggestions on low-power design techniques, energy-efficient components, or potential power sources that could prolong the sensor's battery life would be greatly appreciated.
  4. Data Processing and Analysis: Collecting noise data is one aspect, but effectively processing and analyzing that data is equally important. If you have any experience with noise data analysis, algorithms, or tools that could be helpful in providing meaningful insights to hosts and guests, please share your expertise.
  5. Privacy and Security: Given the sensitive nature of monitoring noise levels in private properties, ensuring user privacy and data security is of utmost importance. If you have any advice on encryption methods, secure communication protocols, or best practices for protecting user data, I would be grateful for your input.
  6. Regulatory Considerations: Are there any specific regulations or certifications that I should be aware of when developing and deploying a noise monitoring sensor for Any information on legal considerations and compliance would be invaluable.
  7. User Experience: Ultimately, the sensor should be intuitive and user-friendly, benefiting both hosts and guests. If you have any ideas or suggestions to enhance the user experience or additional features that would be useful for hosts and their guests, please share your insights.
I would like to express my sincere gratitude in advance to all those who take the time to offer their expertise and advice. Your input will be invaluable in shaping this project and ensuring its success. Feel free to share any relevant resources, case studies, or personal experiences that you believe might aid in my endeavor.

Thank you all for your assistance!

Sounds like you are developing a commercial product and want free engineering advice from a volunteer community representing skill levels from amateur to professionals. The amateurs might give you poor advice. The professionals might not touch this due to liability issues or an expectation of remuneration. Just sayin’. Good luck.

The simplest option that is coming to my mind is Arduino UNO + Grove-loudness sensor. If you want to monitor data, it is also possible. You can save the sensor value in an SD card connected to the Arduino. Later, you can plot those in a graph.

Welcome to AAC.

Not to be a hard case but “sincere gratitude” doesn’t pay the bills. You will get the advice you pay for. If you have prospects to commercialize this, invest in a consulting engineer rather than asking for help from random “experts” on the Internet.

This sort of thing is effectively a solved problem. Everything you need is readily available. A practicing engineer will be able to help you create a sustainable commercial product and what you pay for their time will be easily recouped if the product can be sold.

The one piece of technological advice I will give you is no to use hobbyist sensor modules or development boards for anything but prototyping. You can identify potential chipsets and sensors that can be purchased as dev boards and breakouts, and you can work up test code as proof of concept, but when it comes to actually producing a product you will want to make a PCB of your own and not use the dev board nor the sensor modules.

While making something that “works” is trivial, making something that keeps working and can be legitimately sold as a product takes a range of expertise that only a working engineer can be trusted to do. So, play around with some MCU dev boards and sensors so you understand the parameters, then find an engineer to work with.

Good luck.

No regulatory authority will accepts is data without an up-to-date calibration certificate. Nor will they accept that the noise is "nuisance" without knowing the nature of the noise - i.e. music, DIY work etc. and that requires making recordings.
If you make recordings you (or the user) have to be prepared to deal with Subject Access Requests from anyone who has been recorded, or if the recordings get into the hands of unauthorised person, or if there are no notices displayed that recordings are taking place, be prepared for fines of up to £250,000.

The free advice I wl provide is about the privacy issue. The solution is to in early stages convert the audio amplitude to a DC signal that only reflects the amplitude of the sound level. That will satisfy the privacy paranoid folks, because with no audio there is no intrusion.
And like "Y" explains, engineering services for commercial products are not free.

Unfortunately, that doesn't satisfy the authorities, as the respost is "you can't demonstrate what was causing the noise".
