From data journalism to data sensors

Some examples of  data sensors running on various micro controllers: 

1. Measuring climate in the living room on Raspberry Pi with a SGP30  measuring Co2 and DHT 22 voor temperature and humidity. Display graphics using Node-Red.


Measuring  Co2 with Arduino showing LCD crystal display and  RGB led for different levels of Co2




2. Measuring the weather with ESP32 Fire Beetle with BME280 measuring temperature, humidity and pressure. Display with ESP chart web server.




3. Mini solar panel measuring current with an Arduino Mega 2560, using INA219 and display on serial monitor, plotter and crystal  LCD.
