- Provides a simple temperature logger that grabs data from two APIs - one publicly available to get external temperature and one private (running on ESP8266) that provides internal temperature.
- Internal temperature is provided from ESP8266 via One Wire interface (DS18B20 temperature probe in this case)
- DS18B20 info - measures temperatures from -55°C to +125°C (with ±0.5°C accuracy from -10°C to +85°C)
- Wiring diagram:
- Simple server written in C++ provides a very basic frontend to show current measured temperature [in both Fahrenheit and Celsius] and a /temperaturec endpoint to provide a temp. in degree Celsius
