Hi, the float changed the temperature, but the humidity went tru the roof. Value always around 90.
The uint16_t doesn't change anything compared to no temperature offset. The sensor shows 29C and I would like to get it to 23C.
I have to write it like this: airSensor.setTemperatureOffset((uint16_t) 600);
or am I doing something wrong?

I have just checked. No issues here. I have added an example4 to test. you can manually add the wanted degree change to the measured value ( e.g. 6 for 6 degrees). It will loop to display the SCD30 results and thus you can see the impact.

Hi Paul, thanks for the program. I pt it on the Arduino and checked the reading of the sensor. It startet with 26C. I put in 3 and the behavior of the sensor changed the temperature went up. After 5 min the temperature was 29C. The problem is I didn't want to have 29C, I wanted to have 23C. I put in -3 ant the it changed the number to something wired and the temperature went down to -xxx degrees, very fast. Do you have another idea? Maybe I substract just 3 from the value I get from the sensor and show this number on the display on my Co2-, Temp-, Humidity-meter.

Hi, I tried several differnt things, but no success. It shows still 6 degrees more than all the other thermometers in the house on the balcony, wherever. As soon as I enter a number in the program example 4, the value goes very fast up, it never goes down. If enter 0 it still goes up and stays at whatever it was going to oustside. Very strange but it doesn't affect the CO2 reading. I put it outside it measures the CO2 somwhere around 450, 480, all good.
Any other ideas?

Hi Paul,
I tried it yesterday again an it worked without any problems. I did it the same way like you described in you post. I have set it to zero, and just waited until the reading was really stable. Then I set it to 6, because it was 6 degrees off. Until 10-15 minutes it was stable and now it works exactly the way I want.
Thanks for your help. Stay healthy. Covid numbers in the Netherlands are rising.

Hi, I used the sensor to build a CO2 meter. I used a 1,8" TFT screen that shows CO2, temperature and the humidity. It also changes the colors of the CO2 value from green to yellow to red. My wife works as a teacher and it helps her to determine if they have to open the windows or not. It gives her an idea how much used air is in the room. I hope it helps her not to get Corona, soon. I also think we get it all, but I hope I can get it if some kind of medication is developped.
