You already have the maximum available quantity in your cart.
The Ecowitt WN1821_C Weather Station is a compact display console that shows you air quality and current conditions in the room in one device. The built-in sensor measures CO2 concentration from 0 to 40000 ppm and monitors indoor temperature, humidity, and atmospheric pressure. All values are displayed on a clear 4.9 inch LCD display, which is easily readable from a distance. The station is suitable for the living room, bedroom, children's room, office, or classroom. It helps you easily recognise when it's time to ventilate and how the weather is changing.
The console connects to the home network via Wi-Fi standard 802.11 b/g/n and can upload measured data to online services such as Weather Underground, Weathercloud, WOW, and Ecowitt Weather. You can set the data sending interval to the internet between 1 to 5 minutes. The mobile application is available for both Android and iOS, so you can keep track of the values even when you're away from home. The display also shows the time and date, as well as the minimum and maximum values for the measured quantities. This version is designed for Europe and operates on a frequency of 868 MHz.

It is suitable for anyone who wants to keep track of air quality at home, in the office, or at school and ventilate at the right time.
