Study on the design, build and implementation of circuit in greenhouse weather station

This project was designed to be used in greenhouses. This project consists of Light Level Detector circuit. Temperature Sensor circuit and Humidity Sensor circuit. The circuits are used to measure the condition and surrounding of the greenhouse. This is important in stabilizing the surrounding of the greenhouse to promote healthy growth of plants. This project is aimed for keen gardener to help them in monitoring and maintain the weather surrounding in the greenhouse. Currently in the market there are no similar device containing several gauge and control as in this project. However the weather station equipment is available and is used by many people but it is expensive and it is usually used specifically in a personal computer to interface with. Furthermore there are other similar products that contain the entire sensor but does not show the output to digital 7 Segment display and are also not designed for outside usage. Hence, this project is suitable for use not only in a greenhouse but also inside a house in order to measure the condition in the house. As a result, the user can be aware with the surrounding. This project is more user friendly because the range of scale for the entire sensor is not too big and it will give the exact value of surrounding. This project will give lot of benefit to the user and also it can be used for a variety of function.
