Data logging with Arduino.
The weather script contains the code for basic data logging. The output is shown as a formatted table via serial port, and is best used with a serial port monitor.
The weather-esp-serial script is based on weather but designed for ESP8266 devices. The output is raw-formatted, which may be useful when the data is sent to another program, for example the sonda.js script included in the repository.
The weather-esp-wifi script is based on weather-esp-serial but also sends the data to a ThingSpeak server. Note that some parameters (ThingSpeak API, WiFi network name and password) have to be changed by the corresponding values.
