The system monitors and controls greenhouse parameters like temperature, humidity, soil moisture, and sunlight using sensors, an analog-to-digital converter, microcontroller, and actuators. The sensors continuously sense the parameters and send the data to the microcontroller via the ADC. The microcontroller then takes corrective actions like turning on the water pump, cooler, or lights if a parameter exceeds its threshold. An LCD displays the parameter readings and status of the control actions. Test results found the system provides reliable and accurate monitoring and control with low power consumption.
