I recommend buying a small smart home, which is very convenient to use. There are professional testing instruments to automatically detect indoor air humidity and air quality, and you can view environmental testing results and history anytime and anywhere in mobile APP and applet. My mother takes care of the children at home and checks the environmental quality at home with her mobile phone. If the display result of the mobile phone is not good, she will link the smart home, turn on the fresh air system to control the indoor temperature and humidity or purify the air, so as to ensure the good environmental quality of her and Bao Xiao at home. Small smart home can effectively solve the problems of family humidity and air quality, and solve the two worries at home at one time. It is recommended to buy.
