What the sensor is actually measuring is the electrical resistance of this metaloxide layer. This real time measurement and output of resistance is the first step in obtaining our TVOC reading. The change in resistance across the surface of the sensor is directly proportional to the change in concentration of the target gas(es). The exact degree to which the resistance will change (that is, the ratio or equation that …
Gases as far as possible. Sensors with a storage time of more than half a year, and the first poweron polarization time of more than 12 hours can fully activate the electrolyte and restore the best detection state. 1.

· Milesight produces the AM107 which is also a fantastic alternative but includes an eInk display, an enhanced CO2 sensor, and the ability to measure TVOC (Total volatile organic compounds). These sensors run on battery and send their data back to the cloud using the Isle of Man LoRaWAN network. The sensor is configured to take measurements every 10 minutes.
· The SGP30 has a ''standard'' hotplate MOX sensor, as well as a small microcontroller that controls power to the plate, reads the analog voltage, tracks the baseline calibration, calcluates TVOC and eCO2 values, and provides an I2C interface to read from. Unlike the CCS811, this sensor does not require I2C clock stretching.

activity. The top three graphs show the signal of the MOS VOC sensors and the bottom graph shows the TVOC PTRTOFMS concentration. The top graph shows sensors A and B (two specimen of each type). The yellow and green coloured data shows sensor A. The measuring signal is incomplete for sensor B1
· Since it uses the DART Electrochemical Sensor Technology, even the slightest fluctuations in the levels of CO2 HCHO/TVOC values is detected accurately. On top of that, you get accurate readings about /PM10 particles as well as shown an overall mean value on the screen too. Using this outdoors is even possible as it is powered by a 2000mAh battery which can last up to 8 hours easily.

2. If the sensor reports all data regularly, but sometimes only reports TVOC and CO2 data, you can double check the threshold settings on "Device Settings". If you set the threshold, the sensor will report the data when TVOC/CO2 meets the threshold. Meanwhile, the sensor will also reports all data based on reporting interval.
· CCS811 Air Quality Sensor is an ultralow power digital gas sensor which integrates a MOX (metal oxide) gas sensor to detect a wide range of VOCs (Volatile Organic Compounds) for indoor air quality monitoring with an integrated MCU (Microcontroller Unit).
