Hello guys,
I've been trying to figure how to wire a scd30 sensor to an esp32 but I'm quite a bit confused about how to go about it. I've done some research and got some advice from AI but it confused me even more.
I bought some cat 6 cable but not sure if I should use that because the distances be relativitly short, but the sensor will be in a very humid enviroment, I'll be keeping the esp32's in a watertight box and will design a 3d printed case for all of it with the sensor being on the outside. I was thinking of running jumper wires but later decided to cat 6, using sda - scl on one line each paired with gnd. My question is this,
Can I've 3.3v directly connected to SDA line, twist them, then add a 4.7k resistor that will connect to the esp? how does that actually work? does that make it in series?
