Can I use "YL-69 Soil Humidity Hygrometer" sensor to detect the water parentage of a (washed)cloth.?
Thax.
I would not recommend that sensor for anything because it will corrode fast, see comments here. Use a capacitive sensor instead.
However, I don't think you can measure the degree of wetness of washed cloth that way.
In dependence of your context you may measure the humidity of the air around your cloth to estimate wetness of the cloth.

Some clothing, for example, waterproofs, has had a unique hydrophobic treatment to decrease these surface powers, which empowers them to repulse fluid water better. On the off chance that a water atom has enough vitality it can break the sub-atomic bonds, and turn into a gas particle and detect the water parentage. A free gas particle isn't liable to a similar surface powers and is significantly more ready to get away from the apparel.
write my paper for me service.
most new clothes dryers have two metal electrodes in the drying area.
as clothes pass the resistance due to moisture will be measured and the time of the drying cycle will be controlled.
the part you list is junk. but the concept is very valid and with the correct selection of materials, should last years. I have never heard of the sensors in a clothed dryer failing. but, I think all they are made of is a stainless steel and are thick so that it would take decades of use to wear them out.
