Problems solved by technology
On the one hand, the energy consumption of modern agricultural greenhouses in my country is too large, and the national conditions and national strength are unbearable; on the other hand, the production of agricultural greenhouses is a complicated process, which is a unity of hardware facilities and software technology, and our country lacks corresponding management talents; Or, due to differences in geography, water and soil, climate and even resources, the introduction of foreign systems is not completely suitable for my country's national conditions, and the imported equipment has not been able to give full play to its role, and the cost is high and maintenance is difficult. In view of the main environmental factors affecting the production of agricultural greenhouses for temperature and humidity

Embodiment Construction
[0017] exist figure 1 Among them, the core chip adopts TI's MSP430F427, and the main circuit modules include SHT10 sensor module, liquid crystal display module, lithium battery power supply module, buttons, FLASH, USB communication module and clock module RTC. The temperature and humidity measuring instrument is based on MSP430F427 and uses a digital temperature and humidity sensor SHT10. The liquid crystal display content is 3 lines: the first line is the temperature value display, which can be selected from Celsius or Fahrenheit; the second line is the humidity value display; the third line is on the display screen. The lower right foot shows the current time. The measuring instrument contains two buttons: one is used to switch the machine on and off, and the other is used to switch between Celsius and Fahrenheit temperature display. Use the USB interface to download the program, with manual reset and power-on reset circuit, and at the same time, the system externally expan...

The invention provides a low power consumption agricultural greenhouse temperature and humidity measuring instrument which uses MSP430F427 as a core control device and uses SHT10 as a temperature andhumidity sensor to acquire temperature and humidity. The measurement result is displayed on a liquid crystal display in real time. The measuring instrument is powered by a lithium battery and combinesthe low power consumption sleep mode of MSP430F427 with the timing power off of the sensor SHT10. A single lithium battery which is fully charged can enable the measuring instrument to work continuously and stably for more than 6 months. The system can expand a solar charging function. Temperature and humidity in an agricultural greenhouse can be accurately sampled and measured. The accuracy of temperature and humidity measurement is greatly improved. The low power consumption agricultural greenhouse temperature and humidity measuring instrument has the advantages of simple structure, stablework, low power consumption, and broad market prospect and application value.
Description
Technical field [0001] The invention relates to a low power consumption agricultural greenhouse temperature and humidity measuring instrument. Background technique [0002] The management of agricultural greenhouses in our country has been mainly carried out manually based on experience until the introduction of agricultural greenhouse facilities with advanced environmental control equipment and means from abroad in the 1970s. On the one hand, due to the excessive energy consumption of modern agricultural greenhouses in our country, the national conditions and national strength are unbearable; on the other hand, the production of agricultural greenhouses is a complicated process, which is a unity of hardware facilities and software technology, and our country lacks corresponding management talents; Or, due to differences in geography, water and soil, climate and even resources, the introduction of foreign systems is not completely suitable for my country's national conditions...
