Different values from SEN0321 Ozone I2C Sensors

Hi, I have four Ozone sensors placed in the same place but for some reason readings are really different among them.
One sensor decrease reading and the goes to zero.

This is an screenshot of the values. I am using passive mode

Is it possible to calibrate the sensors?
Best,
Rodrigo

2022-02-18 04:03:44 There are many different kinds of sensors on a sensor board. Here’s a brief explanation of the different kinds of sensors you’ll find on a sensor board. When a sensor board is purchased, it may come with a variety of sensors and connectors. I prefer to follow https://sweetlovemessages.com/how-to-wr ... to-college to learn more information that are very helpful to the students. If you are to change out a part or two on your sensor board, all that is required is to remove the original connectors and replace them with the new ones. If you have no idea how to do this, try reading the instructions on the first page of this website to ensure you have the right kind of connectors. youss1979

2021-03-27 01:44:45 Hi, thanks for the reply. Sensors are placed together. This is another screenshot

What can I do? Is it possible to recalibrate? anonymous

2020-11-10 01:19:51 It seems that the feedback data of two sensors is abnormal. These sensors are factory calibrated. Is the location where your sensor is placed in an environment where gas flow is easy? Have you tried to place the sensor in another position, and have the sensor parameters changed? In addition, I see that the sensor data suddenly becomes 0ppm. Can you check whether the IIC communication of these sensors is normal after the value changes? 309330066
