LTAR Tower 3. EE-181 probe, Adjusted the range to 1V and made sure the wires were connected. It’s sending reasonable values now.
2026-06-01

Adjusted the sonic_azimuth of the 4 towers to 225 degrees. For some reason I had 255 degrees. The correction was made between 12:00 and 13:00. I will adjust the past values to subtract 20 degrees.

On towers 3 and 4:

The EE181 probes were on switched power, I’m going to turn on the switched power at the beginning of the slow sequence and not turn it off again. The first measurement after a restart might be wonky, since the sensor takes 2 seconds to warm up.

On tower 4 we are getting reasonable values, on tower 3 we are getting NaN’s.

I changed the default multiplier on the apogee sensor from -1 to 1, the Apogee voltage or the connections are reversed from the CS310. The correction factor is 100.

Connected ltar tower 4 (BAU) with the wifi connection. Reinserted one heat flux plate and connected the VOLT116 to the datalogger.

Connected the Volt116 to the datalogger at tower 3 (ASP) and updated the heat flux plate calibration factors. Adjusted the azimuth to 255.

Installed the access point at the plant ecology field lab.
