Application of advanced microprocessor in modern agriculture

This book presents a graduated research in UTM Malaysian, that included design of a system to improved crop yields which related to controllable environments, involve efficient use of water and other resources. This system need for automating the data acquisition process of the soil moisture, temperature conditions and various climatic parameters that govern plant growth. A new environmental monitoring and control system is developed which employs Arduino ATmega2560 as well as uses a PID controller with Pulse width modulation (PWM) used together with LM35 temperature sensor and an LM393 comparator chip of the soil moisture module. An LCD unit is used to display the various soil moisture levels for the monitoring operation. The outcome is a stabilized system with minimum error in whole system and has been proven all curves in one chart that¿s displaying the rate of variation between soil moisture contents level and temperature degree against the time in real time data.
