Greenhouse Monitoring System Using Wireless Sensor Networks (WSN) Based on IoT

Abstract

The popularization of greenhouse cultivation in agriculture is becoming more and more common, providing sufficient vegetables throughout the year. However, the traditional indoor temperature and humidity monitoring in greenhouses still requires manual measurement on a regular basis, which is inefficient and has poor accuracy. In order to solve the problem of greenhouse temperature and humidity monitoring, a time-sensitive, convenient, and easy-to-use remote monitoring system for greenhouse temperature and humidity is designed. The system collects data with an Arduino Uno control board and uploads and stores data on the ThingSpeak cloud platform with an ESP8266 control board. The DHT22 high-precision sensor is used as the temperature and humidity data acquisition module. And use the browser or smart phone to view remotely at any time. The analysis and test show that the system has high accuracy and low cost. low cost. It is a reliable monitoring system that has a great role in promoting greenhouse vegetable cultivation
