mildew

Mildew is a small computer serving as a mini weather station. It shows the temperature and humidity in the current vicinity.

It’s currently just patched together from some university scrap components. It’s powered by an ESP8266. Temperature and humidity are collected by a DHT22 sensor. Data is displayed on a 128×32 OLED display.

The DHT22 sensor measures temperature ranges of -40–80 °C with an accuracy of ±0.5 °C, and humidity ranges of 0–100% with an accuracy of ±1%.

notes

I ran into some issues uploading code onto the ESP8266 via Arduino IDE. Using esptool to erase the flash before uploading should work:

esptool.py erase_flash

If you’re using a tiling window manager and you’re experiencing glitches when launching the IDE, try this:

export _JAVA_AWT_WM_NONREPARENTING=1
