reading i2c device (air quality sensor) - Everything ESP8266

18/10/2016· I added the (100000), but it did not change anything. I also toyed around with the clock stretch limit, it seems like the problem is related to that area. With (1000) you're supposed to set it (had to upgrade the ESP arduino library from to before that command was recognized), but even with that I was not able to get a proper …

ZMOD4410 Application Note – TVOC Sensing

01/06/2018· The platinum wire acts as a heater and thermometer simultaneously and is covered in a catalytic substance. The catalyst enables the exothermal oxidation of flammable compounds, which heat the catalyst and platinum wire. This temperature change is measured as a resistance increase of the platinum wire and is proportional to the gas concentration.

Adafruit SGP30 TVOC/eCO2 Gas Sensor

07/12/2020· The SGP30 has a 'standard' hot-plate 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.
