A greenhouse is a building in which plants are grown for commercial or research purposes. These structures range in size from small sheds to very large buildings, with different types of covering materials, such as a glass or plastic roof and frequently glass or plastic walls. But, nowadays, the rising demands for crop production and quality have significantly increased the utilization of high quality and productivity of greenhouse. This project demonstrates the design and implementation of a various sensors for greenhouse environment monitoring and controlling. The PIC16F877A microcontroller is used as the controller for this project which 40 pin IC with 7 analog pins. Among these 7 analog pins, 5 pins are connected with sensors (Soil moisture sensor, pH sensor, Temperature sensor, Humidity sensor, PIR sensor). In this there are two modes of working namely IOT mode and pH mode. The Blynk app is used in IOT mode to control parameters. Solar power is used to run this whole process. Solar battery of 7.2Ah 12V is used to store solar power. Charging circuit is designed separately to charge this solar battery. Once the battery gets fully charged it is connected to run this project
