The greenhouse is climate-controlled structures specially designed for growing plants. Most greenhouse systems use manual systems for monitoring the temperature and humidity which can cause discomfort to the worker as they are bound to visit the greenhouse every day and manually control them. Also, a lot of problems can occur as it affects the production rate because the temperature and humidity must be constantly monitored to ensure the good yield of the plants. Internet of Things is one of the latest advances in information and communication technologies, providing global connectivity and management of sensors, devices, users with information. So the combination of IoT and embedded technology is used to monitor the fields. The thermo-Electric cooler is used to change the temperature regarding the surrounding. Usage of this cooler helps to grow the rare medicinal plants inside the greenhouse. Sensors like temperature, humidity, soil moisture, and Ph are the parameters used to check the healthy state of the soil.
