MSP430FR4133 Microcontroller Air Quality Sensor ... - TI

· This design uses MSP430FR4133 microcontroller (MCU) and Sharp™ DN7C3CA006 sensor. This ultra-low-power centric design of the MSP430™ MCU coupled with DN7C3CA006's integrated analog works in tandem to capture air samples and calculate the air quality index (AQI). From periodic samples, the AQI is calculated and displayed using an 8-character, 14-segment LCD. …

Adafruit SGP30 TVOC/eCO2 Gas Sensor

· The sensor adjusts to the best value it has been exposed to. So keeping it indoors the sensor thinks this is the best value and sets it to ~0ppb tVOC and 400ppm CO2eq. As soon as you expose the sensor to outside air it can adjust to the global H2 Background Signal. For normal Operation exposing the sensor to outside air for 10min cumulative time should be sufficient. If you're …
