IOT BASED GREENHOUSE MONITORING AND CONTROLLING SYSTEM

Abstract

The Aim of this project to design a Green house monitoring and weather station monitoring over IoT System, which can be monitor A greenhouse is a structure that is built of walls and a transparent roof and is designed to maintain regulated climatic conditions. These structures are used for the cultivation of plants, fruits, and vegetables which require a particular level of sunlight, temperature, humidity. The project uses sensors to detect the Soil moisture, Temperature, Light, and Humidity in the Greenhouse and weather monitoring. Soil moisture sensor detects condition of soil whether dry / wet. If the soil of the plant is dry, user can ON the motor pump according to the requirement from web server. The water pump is OFF once the soil becomes wet. Temperature Sensor is used to detect the temperature and humidity readings from the DHT sensor is sent to the microcontroller. The microcontroller is connected to DC Fan switches accordingly. If the temperature is above the threshold value, the microcontroller would send signals to turn ON the Fan. Light Sensor is used to detect the amount of sunlight inside the greenhouse. Reading from the sensor is sent to the microcontroller. If the Sunlight is above the threshold value, the microcontroller would send signals to turn ON the relay. This now processes this data and keeps on transmitting it to the online web server over a WiFi connection. This data is live updated to be viewed on the online server system.
