Summary: Checked LED sensor, fixed pressure sensor.
| Vaira
7-10-2009 Arrived about 10 am. Sunny, hot, dry, little breeze. Looked at deign of NDVI sensor. Removed upward Teflon filter. Two red and two IR LEDs facing up (presumably the same facing down). Resistors are a combination of 249kOhm, 499kOhm and 100kOhms. Siyan called to say Vaisala pressure reading was bad. Sensor was laying in bottom of box. Remounted vertically on side of box reading was okay. I don’t remember manual saying that they must be mounted vertically? I bumped the cal panel for the web cam and had to readjust it to be in frame. |
