I have both a pH and a DO sensor working on one of my data loggers., and I’ve had up to four Atlas Scientific sensors working at once using a sensor bridge: https://atlas-scientific.com/carrier-boards/sensor-bridge/Â I currently have the sensors connected through the qwiic ports, and they seem to be working fine. Here’s my code, there’s a lot of extraneous stuff that I haven’t had a chance to clean up yet, and it’s sending data to thingspeak instead of MonitorMyWatershed:
