2 Flow/Temperature Sensors on Uno Rev 3

I want to use two sensors with the Uno rev 3 to monitor liquid flow rate and temperature simultaneously. This is the sensor I want to use:

I would follow steps similar to the project linked below, except how would I connect the temperature aspect of it?

Can one board handle two of these sensors?

Interesting project but we are not a free design or code writing service. We will be happy help out with your design and or code but first you have to make an attempt to design it, write it, post it and explain what is not working properly.

If there is hardware it is always best to post links to technical information as there are many versions of the same or different items. Since we cannot see your project, my eyes are to weak, you need to post using the language of electronics, an annotated schematic, (best) or a clear picture of a drawing. Pictures never hurt. Frizzing diagrams are not considered schematics here, they are wiring diagrams, great for assembly lousy for troubleshooting. Useful links - check here for reference posts / tutorials

Yes.
Uno has two pins, 2 and 3, for external interrupt. I'm sure you will find people who have used both at once on this forum, and there is a swag of standard codes for using hall effect devices. You DO need to carefully select the sensor for your anticipated flow range.

While the device you show is neat and interesting, I would always choose a DS18B20 over a thermistor. That said, if the temperature window is reasonably narrow, a thermistor should suffice, and plenty of other people use them.

Thank you! Ideally the fluid will see very little to no change in temperature. I was hoping to use this device as a way to record flow rate but also monitor temperature to make sure it's not changing

Hi @emmynm
Welcome to the forum.
@emmynm sensor.
