IOT Based Greenhouse Environment Monitoring and Controlling System

Automation in greenhouse is a method where farmer is able to monitor and control the greenhouse environment automatically from anywhere in the world at any time. Also, the system provides the ability for specific people to monitor and manage the systems remotely. It monitors and controls the temperature, water level in soil and light intensity inside the greenhouse and an IoT app is used to store data. 1.INTRODUCTION [1] Focusing on making a smart greenhouse-controlled environment area to grow plants. By using a low cost more efficient programmable module to detect the climatic behavior inside the greenhouse and controlling the parameters according to their crop production need, through various techniques with the use of board ESP8266 Node MCU module. The parameters that need optimization are the water content of the soil, the light intensity coming from the natural or artificial sources, the temperature and humidity of the field area. The design proposes monitoring by soil moisture sensor, LDR sensor, and DHT22(temperature and humidity) sensor; all these sensors collected the data and given to the NodeMCU module, and then after processing the data all the parameters are controlled via water pump, motors, exhaust system, and light system as per the data calculations. With the help of HTTP protocol, the NodeMCU module is connected to the wireless internet connection or through IoT platforms like telegram bot
