ABSTRACT
The world population is likely to double by 2050; however, neither the area under cultivation nor the availability of water is likely to double to meet the challenge. There are other challenges too, such as reduction in the number of farms and in the number of agriculture workforce. Climate change is expected to further worsen the existing situation. Therefore, in order for humanity to survive, agriculture has to become smart—one way is by integrating Wireless Sensor Networks (WSNs) in different types of traditional agriculture and that too at different levels. In this chapter, we will discuss different types of sensors, their market and different types of WSNs with their application in smart agriculture.
