Martin's Temperature / Humidity Logging Project

This project allows for 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.
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.
Desiccant Plugs
- Spruce Desiccant Plugs (change desiccant to orange type before use)
- Desiccant, white with orange indicator beads (blue desiccant is very poisonous)
- 18mm die (Plastic threads of Spruce desiccant plugs are not conformant, makes it very hard to screw into engine, this die allows fixing the threads)
- Toaster Oven for drying desiccant ($30, works great on lowest temperature setting, however only a 15 min timer, needs to be jammed to stop turning)
