The beginnings of a DIY weather station with WiFI, data logging and multiple sensors. Stage one is two custom shields; One for a pro mini, and a PSU to provide 5v and 3.3v, with another shield for the ESP8266 used for a WiFi connection. This currently now works and is officially an IoT device as it’s sending data to thingspeak.
Later stages will have shields for I2C and SPI busses and for about 8 sensors and a RTC.
