Automated Monitoring and Regulation of User-Friendly Greenhouse Using Arduino

This paper presents an Arduino-based system which automatically monitors the physical conditions of a greenhouse and controls or regulates those physical conditions accordingly. The system measures the humidity, temperature, soil moisture, etc., of the greenhouse and accordingly controls the various components automatically. Different sensors such as soil moisture, temperature, humidity and LDR are used for measuring the environmental data of greenhouse. Measured data are compared with the standard value favorable for the desired plant/crop, and accordingly components such as heater, exhaust fan and water pump are activated with the help of relays. Greenhouse gardening is spreading widely; hence, using this automatic control system will be very useful for farmers and can contribute to improve productivity and quality of crops.
