Automated Greenhouse

The aim of this project was to build a fully automated horticultural system.

Project Description

This project was chosen as a result of an interest in both electronics and horticulture. The automated horticulture system uses various sensors to monitor the climate within the greenhouse. A light dependant resistor is used in conjunction with a bulb. When the light level drops below the set threshold, the bulb switches on. A soil moisture sensor is used in conjunction with a valve and a water reservoir. When the soil moisture level drops below the set threshold, the valve opens and releases the water through a pipe to water the crop. A temperature sensor is used in conjunction with a fan and a servo motor. When the temperature rises above the set threshold, the fan switches on and the servo motor rotates to open the window, circulating cool air throughout the greenhouse. These features of the circuit will be controlled using an arduino. A relay is connected to the arduino switches between on and off for the bulb, valve and fan.

Project Findings

The Automated Greenhouse was an overall successful project. All of the sensor values can be viewed within the Arduino window. The fan reacts to the temperature sensor and the bulb reacts to the light sensor. The valve and the servomotor currently do not work. However, this can be corrected. Both components are faulty and will be replaced.
