A. Product Overview
Temtop C1 CO2 Monitor is a compact indoor air quality monitoring device designed for simple carbon dioxide, temperature and humidity checking. It helps users understand whether an indoor space has proper ventilation and comfortable environmental conditions.
The device displays carbon dioxide level, temperature, humidity, battery status, work mode, buzzer status and health level indication on its screen. It also comes with a magnetic back, vents, USB charging port, bracket and portable body design, making it easy to place directly on a table, use with a stand or attach magnetically.
Temtop C1 is suitable for daily indoor air quality monitoring in spaces where people spend long hours, such as homes, offices, classrooms, schools, meeting rooms and work areas.
B. Working Principle
Temtop C1 works by detecting carbon dioxide present in the surrounding indoor air. The device continuously measures carbon dioxide concentration and displays the value in ppm on the screen.
It also measures temperature and humidity to give users a better understanding of indoor comfort and air condition. The manual lists the carbon dioxide measuring range as 400 to 5000 ppm, with 1 ppm resolution. It also measures humidity from 0 to 99 percent RH and temperature from minus 10 to 60 degree Celsius.
The device has two working modes. In performance mode, the carbon dioxide sensor works every 1 minute. In power saving mode, the carbon dioxide sensor works every 10 minutes. This allows users to choose between faster monitoring and longer battery life.
The carbon dioxide level is also shown through a color indication system. Green indicates good carbon dioxide level from 400 to 1000 ppm, yellow indicates average level from 1001 to 1500 ppm and red indicates unhealthy level from 1501 to 5000 ppm. When carbon dioxide concentration reaches a poorer level range, the buzzer alarm is triggered.
C. Why It Is Used
Temtop C1 is used to monitor indoor carbon dioxide levels and understand when fresh air or ventilation is required. High carbon dioxide concentration usually means that the room does not have enough fresh air circulation.
According to the manual, high carbon dioxide concentration may cause drowsiness, dizziness, loss of attention and cognitive impairment. Temperature and humidity also affect comfort, health, safety and property conditions. High humidity may increase biological contaminants such as molds, bacteria, viruses and dust mites, while low humidity may cause skin irritation, respiratory irritation, static electricity and other discomforts.

- Check indoor carbon dioxide levels
- Understand ventilation condition
- Monitor temperature and humidity
- Identify stuffy or poorly ventilated rooms
