Hello,

After one day of operation, it has stopped working.

I am using the software from https://github.com/DFRobot/DFRobot_OzoneSensor/tree/master

I left the sensor in a clean ozone place (Viella, Spain) for 24 hours. Without disconnecting the sensor, I put it in an ozone chamber with 400 ppb ozone.

After one day, the readings went down until they reached 0. I switched the system off and after one hour I switched it on again and got the same result.

At the 24 hour start, it read 20 and went up to 180 ppb. Now, it reads 0 constantly.
My setup is an original Arduino one. I have checked the connections. When I connect it, the serial port says "I2c connect success !" but the readings are 0.

02/11/2024 23:14:24 Ozone;0;PPB;0; Constantly
02/11/2024 23:04:24 Ozone;63;PPB;0;
02/11/2024 22:54:31 Ozone;324;PPB;0;
02/11/2024 22:44:17 Ozone;331;PPB;0;

What could be happening to make it not work?

Thanks for your advice
