Adafruit SGP30 Air Quality Sensor Breakout – VOC and eCO2 – STEMMA QT / QwiicRoHS Compliant

3,075.00

This is a gas sensor that can detect a wide range of Volatile Organic Compounds (VOCs) and H2 and is intended for indoor air quality monitoring. When connected to your microcontroller (running our library code) it will return a Total Volatile Organic Compound (TVOC) reading and an equivalent carbon dioxide reading (eCO2) over I2C.

The SGP30 has a ‘standard’ hot-plate MOX sensor, as well as a small microcontroller that controls power to the plate, reads the analog voltage, tracks the baseline calibration, calculates TVOC and eCO2 values, and provides an I2C interface to read from. Unlike the CCS811, this sensor does not require I2C clock stretching.
Features
Easy to use
Color: Black
SCL – I2C clock pin, connect to your microcontrollers I2C clock line. Can use 3V
or 5V logic, and has a 10K pullup to Vin
SDA – I2C data pin, connect to your microcontrollers I2C data line. Can use 3V or
5V logic, and has a 10K pullup to Vin
Power Pins: Vin – this is the power pin. Since the sensor chip uses 3 VDC for logic, we have
included a voltage regulator on board that will take 3-5VDC and safely convert it
down. To power the board, give it the same power as the logic level of your
Power Pin: 1V8 – this is the 1.8V output from the voltage regulator, you can grab up to 50mA
from this if you like
GND: common ground for power and logic
You can easily wire this breakout to any microcontroller; we’ll be using an Arduino.
