YUEHISY Air Quality Monitor: WiFi remote monitoring via app
This WiFi air quality monitor is for anyone who wants to know what's in their indoor air—whether you're a new parent concerned about nursery air, or someone working from home who suspects poor ventilation. It gives you a live look at CO2, VOCs, formaldehyde, temperature, and humidity.
Instead of just a number, the color screen changes to alert you when levels rise. You can view the readings remotely in the app, and link it to a smart plug to trigger an air purifier or fan when CO2 spikes. The app shows a graph over time, so you see how opening a window affects the data.
The sensor is sensitive: it picks up a 1 ppm change in CO2 and 0.01 mg/m³ in formaldehyde. The 2000mAh battery lasts for days, so you can move it from room to room. Setup takes seconds—just hold the power button, connect to WiFi, and you're monitoring.
