4690 2020-08-24 Factory none Disposed Disposed none Apogee found manufacturing defects and will send us a replacement NDVI sensor.
4556 2020-07-13 Lab none Tested Lab none I tried to talk to the sensor with the new Apogee SDI-12 to USB dongle and Apogee software - no luck. The same method worked just fine foe the new NDVI sensors. Next will be to return them to Apogee for evaluation.
4523 2020-06-11 Lab none Tested Lab none The two red/far red sensors stopped working on the BA tower. I tested them on the CR1000 in the lab running the BA program and still got no response. I tried the CR1000 terminal to talk to them over SDI-12 and got nothing trying both C1 and C3 ports. I will get a USB to SDI-12 from Apogee soon and will try again with that.
4466 2020-05-19 Bouldin Alfalfa Narrow Band NDVI Reflected Test Removed Lab none Removed from BA because it was sending NANs and brought back to the lab for testing.
4433 2020-04-17 Lab none Installed Bouldin Alfalfa Narrow Band NDVI Reflected Test Installed at BA in the reflected position.
