TOMTOP JMS CO2 Monitor and Controller: CO2 concentration measurement 0-9999 ppm
This CO2 monitor is for homeowners who want to check indoor air quality, especially in rooms like home offices or nurseries where ventilation matters. While many devices focus on security, this one helps you create a healthier living environment by alerting you when CO2 levels rise.
You get clear readings on a display that updates quickly, so you can spot changes before feeling drowsy or stuffy. It measures from 0 to 9999 ppm with accuracy, and the EU plug adapts easily for U.S. outlets. Set it up anywhere—it stands freely on a desk or shelf—and use the micro-USB for low power consumption. The motion alert isn't just for intruders; it reminds you to open a window when levels climb, making your space more comfortable for work or family time.
