Thanks for your replys! Some detail about the measurement
Accuracy - within +/-1 degree centigrade
Rate of reading once a day
Number of sensors - for the trial one (after verification much more)
....
I want to measure the soil temperature say at a depth of 1 m everyday with an accuracy of 1 deg...
I would like to thank you every body again for contributing alternative solutions and suggestions. To put it in a nut shell, I am interested in the following alternatives so far:
1. Using pressure sensor as suggest by Riches … thanks Rich! I would be glad if I can buy a pressure transducer with...
I would like to thank you all of you for your reply. BTW I have gone through the "big" discussion about water depth sensing in this forum ....http://www.eng-tips.com/viewthread.cfm?qid=58310. After going through every post with a lot of pain ... I really couldn't find what I want ... that's why...
I am interested to measure the water depth in a tank above a reference point. The water depth or pressure varies above the reference point from 0 to 2.5 meters. How can this be done in a cheapest way without buying expensive piezometers and data loggers?
I am a novie for electronics ... started building the first simplest circuits. I don't know where I can get them like the resistor, capacitor, LED.... Can anyone help me please. I live in Brussels, Belgium. Can someone knows a supplier in Brussles?
Thanks in advance.
