Agriculture plays very vital role in Indian economy. Near about 70% of Indian population directly depends on agriculture. The main aim of this paper is to provide new engineering technology in an agricultural area which enhances farmers life and Indian economy. Irrigation i.e. well-timed and ample amount of water supply is necessary for agriculture to increase its productivity. This paper develops a small embedded system device (ESD) which takes care of a whole irrigation process and makes farmers life easier. The PIC18F4550 microcontroller interfaced with GSM module works as a brain and several sensors like temperature, level and rain works as eyes of this ESD. The power detecting circuit and battery backup unit take this ESD to next level by informing presence of three phase power supply in the field. The farmer just needs to send predefined commands through SMS from her/his mobile phone to this ESD to carry out irrigation process effectively. If and only if eyes of the ESD sees all parameters are within a safe range, the PIC18F4550 starts irrigation process by starting the irrigation pump. The farmer gets time to time feedback from ESD through SMS about the action that has taken place by PIC18F4550. The GSM module allows farmers to operate and monitor a remotely placed irrigation pump from anywhere far from their field. The free SMS facilities provided to farmers makes it more cost effective. In this way, this new engineering technology makes farmers life easier by providing remotely operated, more efficient and cost effective irrigation system.

The use of renewable energy resources like solar energy is the need of time in countries like India, where energy demand is increasing very rapidly with population. Solar panels are the transducers which convert solar energy into electrical energy. The conventional, i.e. fixed installation of these solar panels on a flat surface is very inefficient and less cost effective solution. This paper comes with an engineering solution to enhance efficiency of solar panel in a very cost effective way. This engineering solution is the dual axis solar tracking of solar panel. The dual axis Solar tracking system for solar panel is the most appropriate way to increase efficiency of solar panel by tracking the sun completely. The proposed system comprises of ARM processor BeagleBone Black -BBB which has Linux OS, Light dependent Resistors (LDRs), Servo motors. The internet facility provided by BBB takes this system to the next level by allowing users to monitor real time solar tracking of solar panels with total amount of electricity generated by these solar panels from anywhere in the world.
