In greenhouses, plants like flowers and vegetables are grown. Daytime sunshine heats the soil, plants and structure itself inside greenhouses. Many farmers struggle to generate respectable income from greenhouse crops as a result of their failure to manage two essential factors that influence plant development and productivity. Temperatures in greenhouses shouldn’t drop unless certain circumstances apply. The effects of high humidity include crop transpiration, water vapour condensation on various greenhouse surfaces and water evaporation from moist soil. These issues are addressed by the monitoring and management system for greenhouses. This study shows how to develop and use a variety of sensors for monitoring and controlling the greenhouse environment. The temperature and humidity sensors, soil moisture sensor, Node-MCU module and water pump are all part of this greenhouse control system, which is run by an Atmega328 microprocessor. The utilization of solar panels ensures constant power supply. Temperature and humidity in the atmosphere are measured through a DH11 sensor. The pumps turn on as the soil moisture sensor detects a reduction in the soil’s water content. Monitoring and managing the system will be simple in this manner. The IOT module (ESP8266) receives data pertaining to these parameters at the same time. Regardless of any threshold mismatch identified, the data is delivered at regular intervals to IOT. The ESP8266 Node-Microcontroller, the DHT11 sensor, a solar panel and a soil moisture sensor are all used in this project. The Wi-Fi module built inside the microcontroller transmits the data to cloud database of the BLYNK app.
