Design And Implementation Of Intelligent Sensor System For Greenhouse

In conventional agriculture,watering,fertilizing,and spraying for crops based on farmers’experience.In contrast,intelligent agriculture could analyze the situation based on real-time data to determine whether the plants in the greenhouse should be attended at this time,i.e.,carry out operations such as watering,fertilizing,and spraying.Intelligent agriculture technology has significantly improved the management level of conventional agriculture,and it could respond effectively and accurately at all stages of crop growth.Information sensor equipment realizes real-time monitoring and collection of the environment in the greenhouse.It uses the intelligent Internet of Things technology to transmit the collected data remotely so that it can provide a scientific basis for agricultural production.The bottom layer of this system uses a wireless sensor network to perceive the environment.In the lower layer,a network is composed of several communication nodes with wireless communication capabilities.The sensors embedded in the chip can detect temperature,soil moisture,light,and so on.These communication nodes are deployed in every corner of the greenhouse,and their primary function is to measure the environmental parameter information in the greenhouse in real-time and transmit the measurement results to the single-chip microcomputer for processing.The primary function of the coordinator is to realize the unified processing of sensor information,including storing node information,establishing a communication network,and so on.The main function of the routing node is to include the nodes that have been applied for joining the wireless communication network into the wireless communication network and to realize the management and maintenance of the nodes that are included in the communication network.The greenhouse intelligent sensor system of this thesis solves the intelligent agricultural business processing flow and realizes the main functional modules such as system irrigation,shading,CO₂,and so on.It has distinct characteristics and advantages.This system uses ESP8266 sensor to achieve the sensing of temperature,humidity,CO₂,light intensity,and automatic exhaust.The innovation of this thesis is that the data obtained by the sensor is passed into the program,and the measured value is compared with the set value in the program,and the corresponding judgment is made to control the air cooler,hot air blower,ventilation fan,sun visor,and CO₂ generation in the greenhouse.Equipment such as filters,irrigation,etc.,make these factors in the greenhouse reach the conditions suitable for crop growth.Through the requirement analysis of the system,the bottom layer of the system uses the ESP8266 chip as the core technology and a set of intelligent sensor systems suitable for greenhouses design in detail.Finally,through the combination of front-end and back-end development,a fully functional intelligent agricultural system is developed.
