Its a AAA project and challenging

Various ultrasonic sensors are connected to front,back and side of the stick. As the obstacle is came in range of the sensor the sensor send the information to the microcontroller.

Our purpose of smart agricultural field monitoring using IOT is to improve the quality of the crop. In that we uses various sensors to measure different field parameter. All these data is collected from the sensor and send to the raspberry pie which will perform the operationlike on off the motor , send an message to the farmer of weather, soil moisture, temperature and water level.
