Outside temperature measured in Warsaw, Poland. Temperature is measured using TC1047A sensor and sent to cloud by ESP-07 module. The other chart shows how much time it took for the module to connect to the network and update the values before it went to
This a private DIY project. The sensor calibration might not be accurate, so the data should not be considered in comparison with public sensors, but rather to compare day to day. Sensors used: Sharp GP2Y1010AU0F for dust, DHT 22 for temp and humidity.
