This looks like a great option. Thanks Shannon for your help!

I have four sensors with heaters, and combined they draw 61.6 mA.

@shicks this is something I am still struggling with, and I am having hard time figuring out. I’ve added some pictures with some of the data I’ve been collecting. It seems that the logger is picking up that there is some diurnal cycle happening, but the values seem to not match what I would expect, or they can be wildly all over the place. If I could get some help with this that would be great.

@srgdamiano do you by chance see where I am going wrong?</p>

Thanks for the quick response Sara. I have not used the build flag. Flags are not something I am familiar with, and I don’t know how to use or adjust them properly. Where would be the appropriate place to make this adjustment in the library?

Great idea! Thanks @shicks!

I’ve attached the specs sheet to this reply. Maybe you can help me interpret it. The following is what I was told from Apogee when I asked about the heaters:

“Regarding the heaters, you do not need to operate them all the time. If the sensors are not in an environment where snow/frost are an issue, the connections for the heater can be omitted entirely. So long as the heater connections are in use (yellow wire on the SL-610-SS), the heater will be on. The only way to turn off the heater is to disconnect the corresponding pigtail. Most people leave them on all the time if their datalogger has enough space available. Not using the heater at all will not affect readings. If the heater is constantly powered, it is able to clear frost/snow in just a couple of minutes (depending on how much).”

Since these are snow sensing stations, the heater will be needed, but as far as I understand it, they do not need to be powered constantly. Am I understanding correctly?

Awesome. The XBee module is an RF module, the XBee Pro S3B. I just remembered, while the apogee sensors I am using don’t require power to make measurements, they do require power for the internal heater. The pyrgeometer heaters, according to the datasheet, draw 15.4 mA and 185 mW at 12 VDC. The pyranometers draw 30.8 mA and 370s mW at 12 VDC. In total there are four apogee sensors (two pyrgeometers and two pyranometers). Do you think it is still a similar situation @shicks that the 4400 mAh battery and 5w panels are sufficient?

@srgdamiano Sorry to bother you on this, but I still need help understanding the issues I’ve had with the Teros library.

[Braedon]

@srgdamiano were you able to look at the cpp code?
