Summary: Fixed the problems of Ta&Rh and Pressure sensors
| It’s a beautiful sunny day. Grasses looked still weak. No tree leaf yet. See cows at Vaira.
Vaira: Everything worked well. I downloaded data. Power status: 14.1, 13.8, 2.6. Fixed the problems of Ta&Rh and Pressure sensors at Vaira: the multiplexer was making click sound when I got there, but the readings of Ta (13.3), Rh (280), and Pressure (66.1) were not correct. I unplugged the wires of pressure sensor, and suddenly no power anymore. I traced power wire all the way to the solar panel regulator box and found the broken fuss. After I replaced it with a similar fuss stored in a plastic bag in Tonzi tower computer enclosure, the readings of Ta (14.1), Rh (38), and Pressure (99.4) were reasonable. |
