Design of Warehouse Temperature and Humidity Detection System

Abstract

With the wide application of temperature and humidity detection system, the requirements and standards of which in different industries and fields are various. After the analysis of domestic and foreign warehouse intelligent temperature and humidity control, the author has found a series of factors of that, and then puts forward a design of scheme of temperature and humidity detection system based on AT89S51, together with a plurality of digital temperature sensor DS18B20 and the humidity sensor HS1101, temperature and humidity detection system is formed.

Hardware Implementation of STM32 Microcontroller-Based Indoor Environment Monitoring System

“…If the return value is zero it means that the reading was successful, if the return value is 1, the reading failed. The file DHT11.h contains mainly port parameters and function declarations, and the code is relatively simple [8]. After successful initialization, the data is collected at 100 ms intervals and uploaded to the OneNET cloud platform for data display.…”
