Oxygen sensor GGC2330-O2 output voltage values

Hi!!
I want to use the sensor with a jetson nano, but I can’t read the information (UART). So, I would like to know the voltage to oxygen concentration conversion (Analog read), I’ve seen the datasheet, but there is only a value range values of 1.5 - 0 V. Also, I’ve tested the sensor and I know that when oxygen concentration decreases the voltage value increases.

Thanks

Hello, here are some suggestions for you

  1. Check whether the UART of your jetson nano can receive and send normally

  2. If you use analog reading, the sensor needs to be ready for about 20 minutes before it can normally read out the results, you can wait a while before reading
