Greenhouse humiture monitoring alarm device based on single-chip microcomputer

Abstract

The invention relates to a greenhouse humiture monitoring alarm device based on a single-chip microcomputer. The device comprises a humiture sensor monitoring system and an alarm system and is characterized in that the humiture sensor monitoring system comprises a temperature sensor, a humidity sensor, an AT89C51 single-chip microcomputer, a data acquisition circuit, an LED display, an A / D convertor, an analog input channel and an alarm circuit. The device is advantaged in that with characteristics of small-scale farmer planting, in combination with the GSM wireless communication technology, the single-chip microcomputer is taken as a processor, the high-precision digital humiture sensor is taken as measurement equipment, problems of low manual monitoring efficiency and unmanned humiture early warning limit value alarm are solved, labor cost is reduced, and demands of storage and analysis of the historical humiture data of the agricultural facility environment can be further satisfied.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a greenhouse temperature and humidity monitoring and alarming device based on a single-chip microcomputer. Background technique [0002] my country is a big country with facility agriculture in the world. According to statistics, the planting areas of solar greenhouses and plastic greenhouses in my country have reached 330,000 hectares and 670,000 hectares respectively. However, the modernization of my country's facility agriculture has been relatively slow. According to regional survey data, the new greenhouse temperature and humidity monitoring system is rarely used due to high cost, difficult maintenance, and low cost performance. Many small and medium-sized farmers or enterprises still use manual inspection of temperature and humidity meters and assign special personnel to guide agricultural production. Low efficiency and high labor costs. Contents of the invention [0003] Aiming...
