Different inputs

Hi!
First of all, I'm pretty new here so i'm sorry if I do something wrong (idk if I can make a New topic for my problem etc).

The thing is, i'm looking for some sensors on the Internet. I want to combine them all in one program.
I was looking for uv radiation sensors and huidig sensors. I already have a temperature sensor.
My question is, do they need to be all digital or analog? Or is it possible to combine these two?

to make use of analogue sensors an analogue to digital converter is needed the arduino uno has 6 of these inputs to use and 11 digital input or output so you can use both what you will be asked here is what exacty you are using these for so enlighten us more about what you are trying to do

Well okay,
I'm joining the CanSat competition in Holland, so I'm going to build a tiny sattelite.
We're going to use an Arduino Pro Micro.
For our first mission (that's for every joining team the same one) whe're going to measure pressure and temperature with an BMP180 Barometric Pressure/Temperature/Altitude Sensor.
This one goes with an analog pin.

For our second mission, we want to measure UV-radiation and Humidity.
We are only beginners in programming, and our teacher said, that it would be a lot easier if we have one kind of sensors, only analog. The problem is, we can't find analog Humidity sensors with a fast response time (since our cansat is going to fall down with a speed of 13 m/s).

Now I'm wondering if it's that difficult if we're just going to use an digital one and combine it with our analog sensors...
Does someone have done this before?

Yes, but it's not analogue. It's digital I2C that happens to use the analogue pins on some Arduinos.

I would say avoid analogue sensors if you can, but your teacher might be an "ouwe knar".

One thing you could do analogue is to measure/log battery voltage against 1.1volt Aref.
