Launchpad_CO2

Environment sensor with CO2, temperature and relative humidity measurement.
The Board is based on TI’s Launchpad MSP-EXP430FR4133 and includes the sensors SHT21 (temperature and humidity) and SGP30 (CO2).

This code is written for IDE Energia (by TI). If you want to use Arduino for this project, you’ll have to add the MSP-libraries.

Following libraries are used, they’ll eventually have to be installed manually:

• LCD_Launchpad (credits: Energia):

• I2C_SoftwareLibrary (credits: rei-vilo):

Note:
SGP30 gets corrupted after switching off power supply, so that no communication is possible. You’ll need to do a software reset after powering up the system.
