ESP8266 BME280 Weather Station
One of our favorite new toys is the ESP8266 WiFi module. A very powerful microcontroller in it’s own right, it’s easily programmed with the Arduino IDE, and uses the same code we have come to know and love. http://arduinotronics.blogspot.com/2017/06/esp8266-bme280-weather-station.html
Do you find the BME280 over-reads temperature because of self-heating? I’m seeing about 2°C error consistently.
