Hardware Description

Monitoring and controlling a greenhouse environment involves sensing the changes occurring inside it which can influence the rate of growth in plants. The System consists of various sensors, namely temperature and light. These sensors sense various parameters – temperature, humidity, and light intensity and are then sent to a computer Labview application via a DAQ Assistant. The application constantly monitors the parameters of the various sensors and verifies them with the predefined threshold values and checks if any corrective action is to be taken for the condition at that instant of time. Once the input value from the sensor crosses the predefined values, the application will:

 Turn on a fan to lower the temperature.
 Turn on the lamp in case of obscurity.
 Turn on a beeper if humidity crosses any of its limits.
