Temperature and humidity sensor is the core
The temperature and humidity sensor is an important component, and it is a key technology for effectively utilizing China's rich biological resources, promoting industry progress, and improving China's industrial competitiveness. The application of temperature and humidity sensor technology covers many fields of national economy such as light industry, food, chemical industry, energy, environmental protection, agriculture, medicine, etc. Let's talk about the effect of temperature and humidity sensor .
The effect of the fermentation environment on the growth and reproduction of microorganisms during fermentation is very significant. Therefore, environmental conditions must be controlled during the fermentation process. Among many environmental conditions, temperature is the primary environmental factor. The temperature mainly affects the life activities of the microbial strains by affecting the fluidity of the microbial cells and the activity of the biomacromolecules. On the one hand, as the temperature increases, the intracellular enzyme reaction speed increases, and the metabolism and growth also accelerate accordingly. On the other hand, as the temperature increases, the biologically active substances ( such as proteins, nucleic acids, etc. ) are denatured, and the cell function is degraded. even death. Therefore, all kinds of microbial strains have a suitable growth temperature. For a certain microorganism, it can only grow normally within a certain temperature range. If it exceeds this range, it will stop growing or even die. Welcome to the company's official website http://
System design principle : The temperature of the device under test is converted into a digital signal by the temperature sensor through a single-chip microprocessor control of the temperature sensor, and then transmitted to the reader/writer through the receiving module, and the temperature information collected by the microprocessor is passed through 485. The communication module is uploaded to a PC computer. A plurality of sensing electronic tags are distributed around the reader, and the temperature measuring terminal can be added, deleted, and moved freely within an effective communication range. The reader is installed in the control center. The control center computer software monitors the temperature change at each point in real time. The temperature monitoring computer collects the operating temperature data of each monitoring point from the temperature measuring communication terminal, and saves it in the database for long-term storage. The temperature change curve is analyzed and once the temperature is overheated, or the temperature rises rapidly to the alarm temperature, the alarm is immediately issued, so that the heat of the whole system can be grasped without leaving the house.
