A greenhouse monitoring and control system based on Zigbee networks was developed. This system consists of greenhouse data acquisition controller and greenhouse remote monitoring and control software. The system could monitor temperature and humidity, soil water content and concentration of carbon dioxide in greenhouse and could save these greenhouse data to database. Greenhouse acquisition controller had two kinds of control modes, including local manual control mode and remote wireless control mode in monitoring center. Greenhouse remote monitoring and control software can collect, display and record the collected data, also can control greenhouse environment. According to the current indoor temperature, the target temperature and the offset temperature, PID control method is used for temperature control in greenhouse. The system is implemented using low power wireless components, and easy to be installed. A good wireless solution is provided by this system for centralized management of the greenhouse group.

The automatic monitoring and control method for aerosol cultivation of lettuce was proposed by real-time monitoring and automatic control of the cultivation environment, on-line detection and automatic control of nutrient solution, and the combination of field control and remote control, which has realized the intelligent management of aerosol cultivation of lettuce based on plant factory. The monitoring and control system of aerosol cultivation, the control model for the spray frequency of nutrient solution and the fuzzy control method for the pH value control of nutrient solution were introduced. The control system has been applied in the agricultural science and technology park, and the results show that the aerosol cultivation of lettuce has advantages over the traditional method.

In order to monitor the process of laser remanufacturing and control the quality of remanufacturing, a monitoring and control system for laser remanufacturing was constructed with its hardware and software. The schedule of the system including signal condition, software interface, sampling and control method, was introduced. Infra-red thermometer with dynamic aiming device was designed to track the molten pool location. Photoelectric sensor was developed to measure the flow of powder. The contrast test results show that the fuzzy PID control system for powder feeding could achieve stable flow.

Day By Day

In Malaysia, most agriculture industries are still using conventional method to operate. All routines in monitoring and control of chicken poultry farm, for example, utilise man power where the source and energy are very limited. However, the demand from consumers towards the agricultural output is increasing day by day and requires more advanced farming technology in order to obtain maximum efficiency. This paper is focused on the development of smart chicken poultry farm to provide monitoring and control of the farm condition. The electronics, embedded systems and wireless technology are integrated with farm monitoring. Using Master-Slave concept, sensors are used to measure the ambient temperature, ammonia and humidity of the hall of chicken poultry for each slave. The sensors’ readings are then transmitted wirelessly over radio frequency by serial communication using HC-12 RF module to master for further data processing. The design process of both master and slave involved the interfacing of microprocessor, ATMEL ATMega328 with several analogue sensors, LCD, buzzer, relay output, monetary push button and light indicator. Based on the readings from the sensors, the microcontroller produced the output which is connected to the fan for better air ventilation in the chicken poultry farm. Furthermore, PID controller has been integrated to optimize the output control method, hence optimizing hall condition which results to better output for the farm. The system has been successfully implemented and tested at Myra Farm &amp; Services, located at Kalumpang, Tanjung Malim, Perak, Malaysia.<em><span style="font-size: 9pt; font-family: Arial, sans-serif;" lang="EN-MY">In Malaysia, most agriculture industries are still using conventional method to operate.
