Application of advanced microprocessor in modern agriculture

Appropriate environmental conditions are necessary for optimum plant growth inside the greenhouse. Improved crop yields are related to controllable environments, including efficient use of water and other resources. Hence there is a 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 Microcontroller Arduino ATmega2560. The system 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 both temperature and soil moisture modules 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. According to this results, the system is done correctly
