Intro

Latest addition to my EnviroSense family is here. I was experimenting how quickly one can put a complete set of sensors, microcontroller and display together leveraging the concept introduced by WEMOS. The result is very promising.

SGP30

This is a I2C Interface TVOC and eCO2 sensor shield based SGP30 from WEMOS. Main specs are:

  • I2C Interface
  • TVOC: 0-60000 ppb
  • eCO2: 400-60000 ppm

SHT30

This one is I2C Interface digital temperature and humidity sensor shield based SHT30. Main specs:

  • I2C Interface
  • Typical accuracy ±3%RH and ±0.3°C

WEMOS 2.4” Touch Screen Display

The display is versatile 2.4-inch color display with integrated touch capability.

Weather Data

The display is nice and big enough that can accommodate the weather forecast data. It is nice to have that feature and thanks to the WeatherMap API it is straight forward to add the feature to the project. Temp Calibrator

Clock from NTP

Thanks to the NTPClient it is also possible to add accurate clock to the project.
