Talking about the Application of Temperature and Humidity Monitoring System in the Construction of Smart City
On December 11, Xinhua News Agency’s WeChat public platform posted an article about the smart elderly care pilot project implemented in Shanghai. The specific implementation of the project is: install a smart water meter for the elderly living alone to monitor the elderly’s water consumption in real time Once the water consumption is less than 0.01 cubic meters within 12 hours, the street level 'one network management' platform will receive the alarm information and notify the community in real time, and community volunteers will come to check the situation of the elderly in time.

It can be seen that smart cities have gradually spread to thousands of households and are actively providing convenience to our lives, and the application of smart water meters is just a small microcosm of smart cities, smart door sensors, Smoke alarms, infrared monitors, temperature and humidity sensors and other technological products have already penetrated into our lives and work, providing convenience for our lives and work. Among them, temperature and humidity monitoring systems based on temperature and humidity sensors are the most common and have been used in various industries.

1. Application of temperature and humidity monitoring system in urban central heating system

As the weather continues to drop in temperature, central heating was started in the north as early as mid-November. To do a good job in urban central heating projects, it is necessary to comprehensively improve the level of heating technology. The remote monitoring of the heating system is an excellent way to solve the above problems. The remote monitoring of the heating system is mainly to monitor the temperature and humidity of the households. The temperature and humidity sensors in the temperature and humidity monitoring system can be used to collect the data in all households. The temperature and humidity data is output through the standard Modbus-RTU protocol and transmitted to the electric heating plant monitoring platform, so that the electric heating plant can understand the temperature and humidity changes in the household in real time, and then collect 485 data through its own PLC to control the on-site water valve according to the actual situation. Community heating balance.

2. Application of temperature and humidity monitoring system in textile processing workshops

The application of temperature and humidity monitoring in textile processing workshops is very important. Changes in temperature and humidity directly affect the tensile strength, elasticity, fiber diameter and friction properties of textiles. The strength of cotton increases with the increase in humidity; the strength of viscose decreases with the increase in humidity. The stretch of most textile fibers The growth rate will increase with the increase in humidity. In addition, static electricity is also a major problem in the textile processing process, which is directly related to relative humidity. Electrostatic discharge poses a direct health risk to people with weak heart or normal heart rate. It can also cause materials to stick together, which is difficult to manage; therefore, the ideal humidity must be guaranteed in the textile processing workshop, and an effective way to humidify the textile factory It uses a compressed air and water spray system to combine compressed air and water to release fine mist and quickly increase the level of humidity required for evaporation. These require reliable and stable temperature and humidity sensors for measurement and control.

3. Application of temperature and humidity monitoring system in greenhouses

The popularity of greenhouses has enriched the 'vegetable basket' of Chinese people in winter. Temperature and humidity are the key factors for the growth and development of plants. Due to insufficient light caused by rainy days or seasonal changes, heat preservation in the greenhouse is affected by the weather, which will become unfavorable factors for the growth and development of plants in the greenhouse. To ensure that the temperature and humidity in the greenhouse are within the growing range of crops, monitoring of temperature and humidity is essential.

The temperature and humidity monitoring system can monitor the temperature and humidity in the greenhouse through the temperature and humidity sensor. Once the temperature and humidity exceed or fall below the suitable temperature and humidity for the crops, the monitoring platform in the temperature and humidity monitoring system can link the indoor temperature in real time. Cooling equipment to ensure that the temperature and humidity in the greenhouse are within the growing range of crops.

With the popularization of smart cities, temperature and humidity monitoring systems are not only used in the above scenarios, but can also be used for temperature and humidity monitoring in the computer room, temperature and humidity monitoring in farms, and drug storage temperature and humidity monitoring. Environment.



are important in ensuring OEM sensor, and the machine is utilised by everyone from environmental monitoring systems to OEM sensor.
