With a weather station, you measure the wind speed, humidity, CO2 level, and air quality. Most weather stations measure the situation both indoors and outdoors. You can read the measured values on the screen. Are you purchasing a digital weather station? Determine if you want a weather station with an app beforehand. You can connect these weather stations to your smartphone or tablet, so you can read all measurements on there as well. When you buy a weather station, it's also important to determine how you'll power it. For example, there are weather stations with batteries and stations that use the power grid or solar power.
