How to Build an Affordable Air Quality Sensor for Your Home

Jun 03, 2019· Finally, the Silicon Labs Si7021 temperature and humidity sensor. These two bits of environmental data are useful. More importantly they’re used by the algorithm in the CCS811 to compute the TVOC and C02. Considering the cost of the CCS811, I’m surprised it doesn’t have these measurements on board but maybe in their next revision..
