 * BuildFlyGo's Temperature / Humidity Logging Project<br>[[File:Screen Shot 2023-11-13 at 4.36.16 PM.png|300x300px]]<br>This project allows logging temperature and humidity at four places. The data is sent via Wifi to a site that allows viewing the data as graphs remotely.<br>[https://www.youtube.com/watch?v=Sh2ZEOab918 YouTube Video]<br>[https://io.adafruit.com/figgyb/dashboards/humidity1?kiosk=true Live Day Graph]<br>[https://io.adafruit.com/figgyb/dashboards/engine-humidity-weekly?kiosk=true Live Weekly Graph]
-* Martin's Temperature / Humidity Logging Project<br>[[File:2023-11-13 08-11-43.jpg|300px]]<br>This project allows logging temperature and humidity at two places. The data along with the time is written to a .csv file on an SD-card. The temperature is +/- 0.1C, the humidity is +/- 1.5%. The microprocessor does have Wifi on board but the software isn't making anything available online right now.<br>The microprocessor uses the standard I2C port for one of the sensors and the realtime clock. A secondary I2C port is used for the second sensor. The standard SPI port is used internally by the display. A secondary SPI port is used to talk to the SD-card. The split allows faster communication. The microprocessor's pins in use are therefore: 2 pins for power, 2 pins each for I2C 1 and 2, and 4 pins for SPI2.

The data along with the time is written to a .csv file on an SD-card. The temperature is +/- 0.4C, the humidity is +/- 3%.
