LOCK DIAGRAM

Fig 2.1: Block diagram of Farm automation system

The above figure shows the Block diagram representation of the new farm automation system using LabVIEW. Figure shows only the important parts of the new system. The different components in the block diagram are,

1.     Sensors

2.     Signal conditioning unit

3.     DAQ

4.     PC

5.     Controllers

Here the sensors will sense the parameter change. Since the output of the sensor is small, we should use signal conditioning circuit. The signal conditioning circuit will amplify the signal. It is then given as the input to DAQ. The DAQ will give the signal to computer. The computer will process the signal & give proper signal to controllers. The controllers will control the process.
