Air humidity and temperature alarm

空气湿度温度报警器

Abstract

The invention discloses an air humidity and temperature alarm comprising a single chip microcomputer minimum system, a temperature and humidity sensor module, a threshold setting module, a display module, an alarm module, and a data storage module. The temperature and humidity sensor module, the threshold setting module, the display module, the alarm module and the data storage module are connected with the single chip microcomputer minimum system. The alarm module includes an LED lamp alarm circuit and a buzzer alarm circuit. The single chip microcomputer minimum system is an STC89C52 single chip microcomputer minimum system. The air humidity and temperature alarm of the invention is equipped with the LED lamp alarm circuit and the buzzer alarm circuit, so that both an LED lamp and a buzzer alarm when the temperature or humidity is beyond a set range, and the air humidity and temperature alarm is very convenient to use and practical. The air humidity and temperature alarm has the advantages of simple structure, low cost, stable operation, high practicability, and strong anti-interference ability.
