The sensor now shows the air quality as a traffic light and the temperature as a value and sends the data via Mqtt to the broker. If the traffic light is red you should ventilate. If the light is yellow it is ok, if it is green the air quality is good. Attention the CCS811 sensor needs a BurnIn for 24h when it is new.

Jul 16, 2021· The TVOC sensor is, for what you get, quite reasonably priced (it’s currently on for just under €50) and can be found in a few online stores in Sweden. By contrast, the Eve Room (v2), is selling for practically double the price, and as of the time of writing, still uses Bluetooth.
This yellow dashboard icon means one or more brake lights is burned out. When this dashboard indicator light comes up, it means you should check the brake pads. A solid yellow warning light means bulb failure is occurring. A flashing yellow indicator light means the …
An independent study showed correlation greater than 90% with BAM. CO2 sensor is high accuracy dual wavelength NDIR CO2 sensor, which self calibrates and allows manual calibration. Temp and humidity are calibrated by a master source traceable to NABL. TVOC uses commercial grade MEMS metal oxide semiconductor sensor and also self-calibrates.
It provides lots of useful information , , PM10, HCHO, TVOC, and AQI. Not sure what AQI is given the more specific other measurements. I like that several of the measurements have a colored box around them indicating green=good, yellow=marginal, and red=bad Did some cooking the other day, the cooking did not go well.
