Netatmo Personal Weather Station allows you to monitor the climate within your home and also the surrounding environment. It comes with 2 modules, for both indoor and outdoor monitoring.
The Weather Station’s Indoor Module measures your indoor comfort by providing vital information, alerting you when you need to air out your home to bring down its pollution levels. We spend 80% of our time indoors, and yet indoor air is often more polluted than outdoor air. The Netatmo Weather Station measures indoor pollution levels through a CO2 sensor, sending you alerts so you can air out your home when necessary and live in a healthier environment.
The Weather Station’s Outdoor Module gives you real-time weather information that matters: gathered right at your doorstep. It measures outdoor temperature, relative humidity and air quality.
Its App allows you to view your data in graph form for real-time tracking of your environment. Observe the cycles and forecast variations around you. It also works with Alexa, giving you the convenience of voice control. For instance, you could ask Alexa the temperature outside to decide if you should bike or drive to work.
Take a look at Netatmo Healthy Home Coach as well. The Healthy Home Coach is lower priced but it only comes with 1 indoor module, instead of 2.
