I would like to compare a few gas-sensors like MQ-131 ozone sensor with one of the sensors from UST - Umweltsensortechnik.
So for example the GGS 5430 T-sensor would be a candidate.
I'm using the Arduino Uno and for better mobility it should be supplied with and external supply like batteries or powerbank.
Because I'm still at the beginning of electronics, I'm really not sure how i should set up my circuit. Especially when planning on using more than sensor at the same time, while they often have different voltages needed.
I would really appreciate it, if someone would take the trouble and show me how to plug it up.
Thanks in advance
