Application of temp and humidity sensor


Temperature and humidity sensor, as the name implies, is a combination of temperature and humidity sensor and transmitter. It is mainly composed of temperature sensor, humidity sensor, measuring circuit, operational amplifier circuit, signal conversion circuit and so on. The temperature and humidity transmitter is an instrument that measures the ambient temperature and humidity. With integrated temperature and humidity probe as temperature measuring element. Collect the change signals of temperature and humidity. It is then converted into a standard current signal or voltage signal output in a linear relationship with temperature and humidity. It can also be output directly through the 485 communication interface. Temp and humidity sensor generally have two installation methods: built-in and external. In addition to measuring signals and conversion functions. Some temperature and humidity transmitters have a local display function. This is mainly composed of a conversion circuit, a display circuit and a liquid crystal digital display.

Temperature and humidity transmitters are widely used in environmental protection, chemical industry, meteorology, medicine, food storage, food processing, greenhouses, electronics and other environments for automatic temperature and humidity monitoring and control. Special items in these industries have very high requirements for temperature and humidity in terms of manufacturing, cargo storage, logistics and transportation. The corresponding process must be completed under the supervision of professional instruments.

With the rapid development of sensor technology, temperature and humidity sensors have replaced manual manual measurements in the past. It is widely used in greenhouses and can accurately monitor the temperature and humidity in the greenhouses. Ensure that the environment in the shed is suitable for vegetable growth. The higher the temperature of the off-season vegetable greenhouse is not, the more suitable it is for the growth of vegetables. And the maximum temperature of different vegetables will vary. If the maximum temperature is exceeded, the growth of vegetables will be inhibited. Fractures in the fruit appear, and if the temperature is too high, it will also affect the respiration of the plant. Lead to unbalanced vegetative growth and reproductive growth, resulting in reduced production.
