1. What are the types of temperature and humidity sensors?
1. Analog temperature and humidity sensor
Integrated temperature and humidity sensor Chemical sensors use digital integrated sensors as probes and are equipped with digital processing circuits to convert the temperature and relative humidity in the environment into corresponding standard analog signals, 4-20mA, 0-5V or 0-10V. The temperature and humidity integrated analog sensor can simultaneously convert changes in temperature and humidity values into changes in current/voltage values, and can be directly connected to various standard secondary instruments with analog input.
2. Type 485 temperature and humidity sensor
The circuit adopts microprocessor chip and temperature sensor to ensure the reliability, stability and interchangeability of the product. The particle sintered probe sheath is used, and the probe is directly connected to the shell. The output signal type is RS485, which can reliably carry out centralized monitoring with the host computer system. It can communicate up to 2000 meters. The standard modbus protocol supports secondary development.
3. Network temperature and humidity sensor
The network temperature and humidity sensor can collect temperature and humidity data and upload it to server. Make full use of the established communication network to achieve long-distance data collection and transmission, and achieve centralized monitoring of temperature and humidity data. It can greatly reduce the construction volume and improve construction efficiency and maintenance costs.
2. What are the applications of temperature and humidity sensors?
1. Application in homes
With the improvement of living standards, people have higher requirements for their living environment. Products such as digital electronic clocks, household humidifiers, temperature and hygrometers on the market are equipped with temperature and humidity sensors to control indoor temperature and humidity at any time. , making the living environment more comfortable.
2. Application in industry
Typical application is in the process of drying wet concrete, using temperature and humidity sensors to record timely and accurately Relevant data provides reliable data for construction. With the rapid changes in science and technology, the application of temperature and humidity sensors is playing an increasingly important role in different fields.
3. Application in agriculture and animal husbandry
In the production of agriculture and animal husbandry, especially the production of some cash crops, if you need to determine the impact of temperature and humidity in the environment on the growth of seedlings, you also need to use temperature and humidity sensors for data collection and monitoring, in order to obtain the best economic benefits.
4. Application in refrigerated storage and transportation
As we all know, in order to ensure the safety of food, vaccines and other food or products during storage and transportation, it is necessary to use temperature-controlled storage and transportation. The humidity sensor monitors changes in temperature and humidity in real time to ensure its quality.
5. Application in automobiles
With the increasingly widespread application of automobile electronic control systems, the demand for automobile sensors will maintain rapid growth. Miniaturized, multi-functional, integrated and intelligent sensors will gradually replace traditional sensors and become the mainstream of automotive sensors. At present, miniaturized temperature and humidity modules are also widely used in automotive electronic clocks.
6. Application in archives and cultural relics management
In high and low temperature, high and low humidity environments, the paper will be brittle or moist and moldy, which will cause the archives to deteriorate. The damage of cultural relics brings unnecessary trouble to various researches. The application of temperature and humidity sensors solves the complicated temperature and humidity recording work in the past, saving the cost of archives and cultural relics protection.
