Abstract

This paper focuses on the indoor temperature and humidity measurement system, and proposes an indoor temperature and humidity detection scheme based on PLC control. The design mainly uses the combination of software and hardware between C language and single-chip microcomputer, collects and transmits data through temperature and humidity sensors, and finally displays data and buzzer alarm on the LCD screen, and the system analyzes the three parts of signal acquisition, signal processing, and signal output. The hardware circuit of this design is simple, the practicability is high, and the tedious and time-consuming process of manual testing is greatly eliminated, and the market prospect is good.
