thanks for your reply...
ya ...indeed it all about automation ...i just want to create a long soil moisture sensor... while get the data via my nodeMCU (microcontroller)...
i don't want to go into electrical engineering either... i just want to make a sensor all by myself...
i already used...
Thanks everybody...
it looks i am at an awesome place to find help...
as for insulating my device...i am thinking of varnishing or painting(waterproofing) the plates of my capacitor plates...
for buying capacitive moisture sensors...i already have those...but now i want to make a long...
in my experiments i will be using a multi meter...
for my project node MCU
...could you please tell me what and how and why make osc ... and frequency,...
i didnt quite understand it
thanks Baluncore for your reply...i will be adding other sensors along with this sensors...like pH,temp...that will make it work, i guess...neutron probe will make it an expensive product... and a few points you made made me to think about a few things...anyways...should i calculate change in...
thanks Baluncore for your warm welcome and reply
actually i am planning to make long capacitive soil moisture sensor...
where i will be collecting data by calculating change in dielectric, for i recently learned that change in wetness leads to change in dielectric constant...am i right??
hi everyone!
i am not into physics, but need it now,i am a programmer workin on an IOT project...so kinda need help.
i want to use a capacitor to see what passed between two plates...knowing, it is the change in dielectric after certain intervals...how do i measure the change at the other...
