I plan to use MQ131 sensor from NCD. The product link is: https://store.ncd.io/product/mq131-ozone-gas-sensor-adc121c-12-bit-adc-i²c-mini-module/.
In the website they said the detection range is 10ppb-2ppm. However in the datasheet they provided in here: https://media.ncd.io/sites/2/20170721134616/MQ131.pdf said different thing, wherein the range is only 10-1000ppm.
Anyone here can help me to answer my confusion? because measurement range is very important for my case.
