[time-nuts] Question for my new GPSDO

[Tobias Pluess]

Well, temperature measurement is anyways not the key point of my project, so I will use any ordinary digital temperature sensor. The BME is very nice, but perhaps overkill for this application.

I want to have a temperature sensor mainly because I plan to send the temperature and OCXO current readings, together with timing readings, on a serial port. At some day I plan to look how Lady Heather interprets that data, such that I could use it to monitor the stability of my hardware.

The BME280 does temperature, humidity, and pressure.  They are very nice.  Beware of BME280 boards sold on Ebay, etc.  A lot of sellers ship BMP280s.   One way to tell is the BME280 is in a square package and the BMP280 is more rectangular.

Also be aware that some BMP/BME280 libraries seem to have some error in their humidity calculation code and produce incorrect results.

>The very similar BME280 also measures humidity
