For security reasons, an e-mail has been sent to you acknowledging your subscription. Another nice element to this sensor is it comes with an SHT31 temperature and humidity sensor already built in. Then you need to update code.py with the example script. The SGP30 does have built in calibration capabilities, note that eCO2 is calculated based on H2 concentration, it is not a 'true' CO2 sensor for laboratory use. An external humidity sensor is required and then the RH% is written over I2C to the sensor, so it can better calculate the TVOC/eCO2 values. The third trick here (the double-click) has helped me, but it seems like a cludge. We'll send you information about new product launches and special offers!
