Let's Control It

hi there,

does anyone have an idea how to integrate this VOC sensor. it has an i2c interface. it seems obvious that it needs some re-coding but in general should be doable due to i2c interface.

her is the datasheet https://cdn-shop.adafruit.com/product-f ... S-5524.pdf

it sells for just USD 6,80 on ebay.

help is appreciated, since i do have no programming skills
regards and thanks

hey guys,

After digging a bit deeper I found the solution. the sensor itself has i2c but the breakout module delivers analog signal which can be processed by an ADC. this is fine!

Curious, I only get values between 10 and 30 on an esp ADC, which translates to 0,01 to 0,03V with 1024 Digits (10bit) and max 1V Input on the ESP. this is something I don't really believe...

does someone have an idea on that?

regards
karl
