Description

Technical Field

[0001] The utility model relates to the technical field of temperature, humidity and carbon dioxide detection, in particular to a novel temperature, humidity and carbon dioxide detection sensor. Background Art

[0002] A greenhouse, also known as a hothouse, is a facility that allows light to pass through, keeps heat (or heats up), and is used to cultivate plants. In seasons unsuitable for plant growth, it can provide a greenhouse growth period and increase yields. It is often used for cultivating or raising seedlings of warm-loving vegetables, flowers, trees, and other plants in low-temperature seasons. There are many types of greenhouses, which can be further divided into many categories based on different roof truss materials, lighting materials, appearance, and heating conditions. Types of greenhouses include planting greenhouses, breeding greenhouses, exhibition greenhouses, experimental greenhouses, catering greenhouses, and entertainment greenhouses. The design of greenhouse systems includes heating systems, insulation systems, cooling systems, ventilation systems, control systems, and irrigation systems. A greenhouse is simply a simple structure of plastic film and frame, with very few internal facilities, not as high as those required for a greenhouse. Therefore, strictly speaking, greenhouses have higher equipment requirements than greenhouses, and more advanced instruments may be needed to strictly control the temperature.

[0003] In addition to temperature control, greenhouses also need to control humidity and air volume. However, currently, these tests are performed separately, with some testing temperature, some testing humidity, some testing CO2, or some testing temperature and humidity together. This requires the use of auxiliary testing in greenhouses, such as placing a separate CO2 tester alongside a temperature and humidity tester. This takes up additional space, wastes resources, and increases costs.

[0004] Therefore, the existing temperature, humidity and carbon dioxide detection technologies need to be further designed. Utility Model Content
