Hello, I am trying to use both the SCD30 CO2 sensor and TH02 high accuracy mini temperature sensor on my seeduino. Both work fine on their own, no problem. But when I connect both, suddenly my SCD30 sensor’s isAvailable() does not return true anymore. I tried looking to see if the i2c address is perhaps te same, but it doesn’t seem like this is the case.
How can I get both to work at the same time?
Any suggestion on how I can tackle this problem? I’m a relatively experienced programmer so I’m willing to dig into the code, but I’m a novice when it comes to electronics. Right now I’m just not sure where to begin to look.
These are the two sensors I’m using:

This is a compatibility problem between I2C devices, which cannot be solved by software.You can connect two sensors to different I2C devices.
