Web-Based Monitoring and Control System

The system consists of sensors, a microcontroller, actuators and a communication module which monitor and control several parameters of the growing chamber: temperature, water pH and light intensity. The sensors that we used in this research are the LM35 (temperature sensor), a pH sensor, and an LDR (light intensity sensor). The microcontroller was programmed using Arduino IDE. On the actuator, there are two relays that activate the ultrasonic mist maker and fan on specific cycle time intervals.

• This system will be able to measure a growing chamber’s temperature, pH, and light intensity.

• This system uses a control timer for ultrasonic mist maker and fan activation.

• Sensor measurements will be displayed on a website.

• The system is designed to transmit data using GSM/GPRS.
