A greenhouse is a structure that is built of walls and a transparent roof. It 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, and soil moisture. Arduino & IOT based Greenhouse Monitoring and Control system Project is designed to maintain these conditions in the greenhouse.
IOT and Arduino based Greenhouse Environment Monitoring and controlling project use four sensors to detect the Temperature, Light, Humidity, and Soil moisture in the Greenhouse.
A temperature Sensor is used to detect the temperature inside the greenhouse. Reading from the sensor is sent to the microcontroller. The microcontroller is connected to different relays. One of the relays is connected to a blower. If the temperature is above or below the threshold value, the microcontroller would send signals to turn ON the Fan.
A 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 which would, in real-time, be a ‘shade’ that would reduce the amount of Sunlight. For demo purposes, we have connected a DC motor to replicate a Shade.
Similarly, the Humidity sensor is used to detect the humidity value and the Soil moisture sensor (two probes dug in the soil) is used to detect the soil moisture. If the humidity value detected by the sensor is above the threshold value OR if the soil moisture reduces, the microcontroller would turn on the blower to decrease the humidity and will open the water outlet to increase the moisture in the soil. For demo purposes, we have connected a DC motor in place of the blower and water outlet.
At the same time, data regarding these parameters are sent to the IOT module (ESP8266). The data sent to the IOT is sent at regular intervals irrespective of any threshold mismatch found.
ESP8266 is a chip used for connecting micro-controllers to the Wi-Fi network and making TCP/IP connections and sending data. Data, which is sensed by these sensors, is then sent to the IOT.
The components used in the IOT and Arduino Based Greenhouse Environment Monitoring and Controlling systems are
The Prerequisite for this project is that the Wi-Fi module should be connected to a Wi-Fi zone or a hotspot. This project is also implemented without the IOT module. In place of the IOT module, we have used the GSM module, by which an SMS is triggered.
