Abstract: In this paper we are trying to explain few of the agricultural process such as Water pumping with a precise level as required by the crop. In our system we have automated the water pump to pump the water whenever the prescribed water level or humidity of the soil goes down below prescribed threshold level. For this case we use a water level sensor & Humidity sensor. If the water level is increased beyond the prescribed level during rain or flood, our system automatically lets the extra water and recycles them back to the water tank ( if required ).Our system also senses the wind speed to predict any storm & other natural calamities and warns the farmer by sending him an SMS using a GSM Modem. For safety purpose we also have fire and temperature sensors to alert the farmer on any kind of such eventualities. The prescribed water level for a crop varies depending on different crops and nature of the soil, so we have developed a user interface to feed the type of soil and crop to automatically set the water level. The farmer is able to control and monitor the field using his PC which is connected to the control system using Zigbee. Eventually a microcontroller was chosen for the heart of the system. A PC based solution could have been designed easier but a microcontroller based solution meant that the system was more independent and hopefully more reliable, with cheaper running costs.
