Abstract

The invention belongs to the technical field of life service and particularly provides a key switch capable of measuring temperature and humidity. The temperature and humidity conditions of a key switch are sent to a user through temperature and humidity sensors to be used by the user subsequently. The key switch is formed by a 220V AC connection wire, an external connection equipment reserved wire, a transformer, a rectifier circuit, a switch key, a temperature sensor, a humidity sensor, an A / D converter, a processor, an LCD drive circuit, an LCD display circuit, and a housing. The problem that people can not accurately know the temperature and humidity conditions of multiple positions of a living place in daily life is solved, and the key switch has the characteristics of accuracy and real-time performance.

Description

technical field [0001] The invention belongs to the technical field of life services, and specifically provides the function of feeding back the temperature and humidity where the key switch is located to the user through the temperature and humidity sensor for subsequent use by the user, and solves the problem that people cannot accurately know where they live in daily life The problem of temperature and humidity conditions in multiple locations has the characteristics of accuracy and real-time. Background technique [0002] The key switch is a constant item that feeds back the temperature and humidity where the key switch is located to the user through the temperature and humidity sensors, so as to facilitate the daily life of the user and improve the quality of life of the user. [0003] The main ways to detect temperature and humidity are as follows: [0004] 1. Traditional thermometers and hygrometers: Since traditional thermometers and hygrometers use thermal expansio...
