BlueDot SGP30 Board

The SGP30 is a digital multi-pixel gas sensor from Sensirion, designed for air purifiers, ventilation systems and IoT applications. The sensor contains a temperature controlled micro hotplate highly sensitive to the presence of Ethanol and H2, and from these measurements it calculates the two air quality signals TVOC (Total Volatile Organic Compound) and CO2eq (Carbon Dioxide Equivalent).

Features:

• 3.3 V and 5 V Power Supply. The on-board voltage regulator accepts anything from 2.6 V to 5.5 V to supply the SGP30 sensor with a constant voltage of 1.8V. 
• Data Transfer with both 5V and 3.3V devices. While devices like the Arduino Uno interpret a 5V signal as a logic HIGH, the SGP30 uses 1.8V as a logic HIGH. The on-board logic level converter translates the 5V signals into 1.8V signals and vice-versa.
• I2C Communication. The sensor communicates through the I2C protocol using 0x58 as the default address.
