I am working on a gas flow sensor SFM4100. It's communcation protocol is i2c. And according to gasses bus adresses are changing. For o2 gas, address is 2.
When I connected the all pins according to datasheet , raspberry pi doesn't detect i2c address.
I tried both
sudo i2cdetect -y 0 and
sudo i2cdetect -y 1
What is the reason of that ?
Also, my pin connection . Any help is appreciated.
