Hi everyone,
I want to develop a project about to measure the flow of the urine when it falls to a deposit.
However, I would like to know if there is a way to not use wire connected to the arduino because the patient has to introduce the urine while using the toilet, so the wire would be unhygienic and uncomfortable. I do not know if I could install a sensor flow in the deposit with a Wifi module and a battery, but without the wires of the arduino. Could someone help me? Best regards.
Your topic has been moved to a more relevant forum category that Projects/Showcase where you originally posted it. Please be careful when deciding there to start topics
How much experience do you have in designing medical related devices? What you are considering is a USE ONCE AND THROW AWAY device. What difference wires make is not the main concern. Can you make your device in quantity so it can be cost effective to use only once?
How do you know if wires are not the main concern? I am trying to say that wire are really uncomfortable to make pee while they are placed in the inner of a toilet, and I am not considering A THROW AWAY DEVICE. I think that the point is not if I have experience or not in medical devices.
Do your toilets have seats and lids? I do not understand the setting on wire problem!
Do you just want to measure flow (volume total) or flow (volume per second),
or also color and pH and ...
About flow
The urine comes in a siphon of which you know the volume and temperature.
As the urine comes in water the temperature in the siphon will rise.
If you know the rise in temperature you can estimate the amount.
You should build a test setup in which you test a 20 different volumes (@37C) and each volume 5 times.
Put the data in Excel - volume vs temperature rise
Let Excel find the trendline and you have a first order measurement.
Assumption: waterproof DS18B20 is also urine proof.
By tracking the moments the temperature starts and stops to rise you might get an indication of volume per second.
Thank you, but I do not need to know the temperature, I only need to know the volume per second, in other words, I need to monitor in real time the flow of the urine, only that information, it is like a uroflow test.
You aren't reading carefully. It's not about needing the temperature:

You seem to be going in circles, when the wire is the problem. You can use AWG 36 wires with nylon insulation since we are dealing with signals. Why not fix the problem?
