Temperature and humidity detection and alarm system based on single-chip microcomputer

Abstract

The invention discloses a temperature and humidity detection and alarm system based on a single-chip microcomputer, which comprises a single-chip microcomputer and is characterized by further comprising a temperature sensor, a humidity sensor, a display module and an alarm module, wherein the temperature sensor and the humidity sensor are connected with the single-chip microcomputer through an ADC(Analog-to-Digital Conversion) module; and the display module and the alarm module are connected with the single-chip microcomputer. The temperature and humidity detection and alarm system based on the single-chip microcomputer meets the requirement of user diversity, and also meets users of different classes at the same time, not only can be installed in residential houses to use, but also can be installed in crop greenhouses or warehouses to use. The temperature and humidity detection and alarm system performs early warning on a risk by using an alarm circuit, thereby enabling the users toquickly know that the environment is abnormal. In addition, the temperature and humidity detection and alarm system realizes wireless transmission of signals by using a ZigBee module, and avoids tedious construction and inconvenient use brought about by wired transmission.

Description

technical field [0001] The invention relates to the technical field of indoor or outdoor air detection, in particular to a temperature and humidity detection and alarm system based on a single-chip microcomputer. Background technique [0002] At present, with the continuous advancement of my country's urbanization process, more and more combustible gases such as coal gas are used as clean energy in the daily life of urban residents. While they bring great convenience to people, they also cause serious safety hazards. The main component of household gas is CO, and once it leaks, it is very easy to cause fire, even explosion and other accidents. Not only cause very serious economic losses, but even threaten life safety. [0003] However, our country is on the road from agriculture to cities. The rural population still accounts for the majority, but the rural population is distributed in all walks of life across the country. There are rural populations living in cities, towns...

Problems solved by technology

Greenhouse is an important part of modern crop production technology. The control of modern greenhouse is mainly the monitoring of temperature and humidity. However, some backward greenhouse environment monitoring systems have poor stability, low sensitivity and high cost. The temperature and humidity in the greenhouse cannot meet the needs of crops. The growth requirements will be extremely unfavorable to its growth, and it no longer meets the development requirements of modern agriculture.
