Applicable scenarios:
1. Install a CO2 and temperature detector in the breeding house and connect it to the fan to monitor the above data at any time. When the CO2 concentration exceeds the standard, the monitor will alarm and start the fan to automatically replace fresh air, while monitoring the temperature and ventilation rate of the pen at any time
2. Installing a CO2 detector in a plastic greenhouse can ensure timely alarm when the CO2 detector concentration is insufficient, so as to use gas fertilizer, ensure vegetables, fungi, flowers, Chinese medicine, etc. are put on the market early, high quality and high yield
3. When school teachers are in class, if the window is not opened for a long time, the CO2 concentration will increase, reducing learning efficiency. If a CO2 monitor is placed in the classroom, the air quality can be guaranteed, thereby improving learning and work efficiency, preventing the spread of infectious diseases, and ensuring public health and safety
4. Placing carbon dioxide and temperature monitors can monitor the carbon dioxide concentration and indoor temperature in these public places at any time, and adjust the ventilation rate and temperature as needed, which will save a lot of resources and expenses
