New Products 8/11/21 feat. Adafruit SCD-41 – NDIR CO2 ...

2021-08-14· Adafruit SCD-41 – NDIR CO2 Temperature and Humidity Sensor – STEMMA QT / Qwiic. The SCD-41 is a photoacoustic ‘true’ CO2 sensor that will tell you the CO2 PPM (parts-per-million) composition of ambient air. Unlike the SGP30, this sensor isn’t approximating it from VOC gas concentration – it really is measuring the CO2 concentration ...

ESP32: BME680 Environmental Sensor using Arduino IDE ...

The BME680 sensor module is a 4-in-1 digital sensor that combines gas, pressure, temperature and humidity sensors. The BME680 contains a MOX sensor that senses the presence of most VOC gases. This sensor gives you a qualitative idea of the sum of VOCs/contaminants in the surrounding air. For this reason, the BME680 can be used to monitor indoor ...

mute&vent - mute button with CO2 warning |

2021-06-18· VOC sensors are cheaper and can output "equivalent CO2", essentially just multiplying the measured volatile organic compounds by the average proportion of exhaled VOCs to CO2. These could be confused by your furniture, a strong drink and many other sources. They just make you vent more often then, so no issue. Packaging is small enough for any device. There are also some nice …
