Design of Temperature and Humidity Measuring System Based on Raspberry Pie

Abstract

With the rapid development of Internet of things technology, temperature and humidity treatment has been applied to network wireless technology, network data processing technology. The temperature and humidity measurement system based on raspberry PI is designed with DHT11 sensor for measurement, the micro-computer raspberry PI as the main control, and the OneNET platform for data processing, together with the program design, to maximize the OneNET mobile APP to view the data drawn by the image. The system is designed to use networked processing to remotely monitor the data flow of the sensor and send alarm commands to the mobile phone through the highest threshold set by the program. Experimental results show that the system design is relatively simple in terms of structure deployment. It can realize remote command sending by mobile phone APP and know the temperature and humidity value within the range of the measurement area at any time. It can effectively prevent potential safety hazards caused by excessive temperature and humidity through prompt message processing.
