A sensor can be identifying the environment changes from the surrounding of the device. In the earth who are live plants, animals and human beings have some basic sensing behavior by nature, so those approaches and behaviors we fallowed and implement to nonliving things. These are the major behavior we identify from the sensors like light, sound, motion, temperature, pressure, acceleration, position, Object presence, and Air. Here I'm sharing few components 1. Temperature Sensor Temperature sensor sensing the circumstance of temperature in the installed places. 2. Ultrasonics Sensor Using ultrasonic to identify the obstacle distance in front of the device and based on the data we can manipulate the application. 3. Pressure Sensor Find the pressure value on the device to you gave the pressure on it. 4. Water Level Sensor A water level sensor sensing the water level in the water tank and based on value trigger the applications.  5. Motion Sensor The motion s

                 In this question we have two options, The first one is natural farming and another one is chemical farming. Both are the way to start an agriculture startup. Before we jump into the topic we have to look at more important things like Financial, Yield, quality of food and Marketing these are the very challenge we face. Chemical Farming 1.
