Description

Technical Field

[0001] The utility model belongs to the technical field of vegetable planting, and in particular relates to a temperature and humidity monitoring device for a vegetable greenhouse. Background Art

[0002] A vegetable greenhouse is a frame-covered structure with excellent thermal insulation performance. It allows people to eat off-season vegetables. Generally, a vegetable greenhouse uses a bamboo or steel frame, covered with one or more layers of thermal insulation plastic film, thus forming a greenhouse space. The outer film prevents the loss of carbon dioxide produced by the growth of vegetables inside, giving the greenhouse a good thermal insulation effect. During the use of the vegetable greenhouse, in order to check the internal temperature and humidity well, a monitoring device will be installed for real-time monitoring.

[0003] A Chinese patent discloses a temperature and humidity monitoring device for soilless cultivation of greenhouse vegetables (CN209135051U), which includes a control system and a monitoring system. The control system includes a temperature control system and a humidity control system. The monitoring system includes a temperature and humidity sensor. The temperature control system includes a water heater. The utility model is provided with a single chip microcomputer, a water heater, a valve, a first pipeline, a recovery box, a water pump, a second pipeline, an atomizing nozzle, a temperature and humidity sensor and a temperature and humidity alarm. When the temperature and humidity in the greenhouse are detected to be abnormal, there is no need for workers to adjust the temperature and humidity. The atomizing nozzle can atomize water, thereby facilitating the humidification of the greenhouse body and reducing the workload of workers. The temperature and humidity sensor can monitor the temperature and humidity in the greenhouse body and transmit the monitored information to the single chip microcomputer. The temperature and humidity alarm can alarm when the temperature and humidity in the greenhouse body reach the preset alarm value. With the increase of the use time of the current temperature and humidity monitoring device, water droplets will adhere to the outside of the sensing element on the monitoring device. When monitoring the temperature and humidity at different positions, the monitoring result is easily deviated due to the water droplets, and it is not convenient to change the height of the device during use, resulting in incomplete monitoring and inaccurate monitoring results. Therefore, a temperature and humidity monitoring device for a vegetable greenhouse is provided. Utility Model Content
