I want to make a sensor that detects liquid and then sends an audible signal. It must be DC voltage because it needs to be portable and battery operated, the problem I have is that it needs to be very small and I can not buy one from the shelf.

Hi,
I hope you are doing well. I have extensive experience in embedded system design and development.
I have understood your requirements which are to develop a liquid detector system.
I would like to know dimensions of the systems you are looking forward.
Price Negotiable.
Please send me message for further discussion.
Looking Forward,
Khawaja

Hello,
I am Anthony from Sri lanka. I have 7 years of experience in the filed and I am very much interested in your project.
Why you should hire me ?
* As a full time freelancer I have my own PCB fabrication work shop and testing lab. So there is no problem doing live tests with you after the device has been developed.
* My workshop is equipped with CNC machine, FDM 3D printer and DLP 3D printer. So there is no problem designing and printing plastic parts you required.
Please contact me if you are interested. Thank you
Anthony
hi there i am an electrical engineer. i have 8+ years of related to arduino development and circuit designing. we can design your solution. let us know if you are interested.
Hi,
Can you give more information about your application, so I can give you an extimated price and time frame for development.
What kind of liquid do you want to detect?
How loud should the audible signal be?
How long should the battery lasts?
Best regards,
Adriano
Hello,
I study electronics at Politecnico di Torino and I can design such thing for you. My main concern is what will be the event of it ? Will it be like water level sensor or will it be like the wiper sensor which its fucntion is only if ther is water or not ? Please give more details I will be glad to help you.
Best regards

Circuits like the one in its description can be made in very small dimensions for the detection of liquids and self-supplied acoustic warning, also because their consumption in a state of rest is zero, so a very small battery is sufficient. happy to collaborate with her if selected.
Dear sir,
I have a 7+ year experience in schematic design, PCB design and Firmware development.
I have a completed many Electronics project please check my portfolio.
By looking at your requirement i am interested to with you .
Looking forward to your valuable reply.
