Hi. Another problem I have to deal with concerns the pressure transmitter as in the link : https://a.aliexpress.com/_mNJzyFr.
Somehow, I cannot find out what is the relationship between the length of this unfortunate tube and the accuracy of the readings. So far, the idea is to run the whole thing on an ESP 8266 and via wifi the data will be visualised on the virtuino. The voltage output solves my communication problem with the Arduino. The transmitter itself can be connected to the Arduino on short cables so voltage drops will be negligible. The range of 0-200 KPa is, as far as I remember, 20 m water column ...Just what about the accuracy of the readings? Has anyone had contact with such a device? Unfortunately in my case the tube length will be about 11 m and I am wondering about the sensitivity of the system.
And one last question. Does the material of the tube have any effect on the reading?
Greetings
