MiniWeather is a small Arduino project for a ESP8266 with a small OLED + DHL11 sensors. It shows the temperature in Celcius and the Humidity. Can also connect to a Wifi network and make the values available there.
Available from places like Banggood. Look for "Geekcreit ESP8266 IoT Development".
Was coded for fun and the challenge to use PlatformIO.
Install PlatformIO. There is a Makefile
with which one can do
make build
build binarymake install
(build and) upload to a device if connectedmake clean
clean directory
Replace the network SSID and Password. Comment the #error
line before building first time.
