More on the Lwet sensors

OK - with the help of Tom, Walt and Nik we re-wired the C sensor and it is now giving sensible resistance output data (brown line) so three sensors are now mounted and wired and programmed successfully to the data logger and the remaining sensor is almost ready to go, however it is a little different as it links to a different data logger and gives % data rather than raw output so that will make comparisons difficult. Below is a graph of test data from my office, and below that is a photo and a diagram of the sensor set up.
