Daylight harvesting is becoming increasingly important in the design and implementation of commercial lighting systems. Being able to integrate the natural light from windows with flexible, controllable sources of lighting helps improve the work environment and cut energy bills. Being able to have closer control of the lighting systems in a commercial environment is a key element to this strategy and energy harvesting can play an important role. Being able to have flexible placement of control pads for a commercial lighting system is an important requirement as office space is regularly reconfigured as existing clients grow and change their requirements and new clients have new requirements.

  This term was coined by Honeywell, USA in 1985. The first generation of instruments like flow meters were mechanical devices. The next generation used electronics for improving performance. With electronics, adjustment of range, span, zero adjustment etc. could be carried out with potentiometers. (i.e. ease of setting parameters was achieved) In some cases functions like linearization, annunciation (exceeding process limits) etc. were also integrated. With the help of 4-20mA transmitter, data transmission over longer distance was made easy. There was a considerable jump in technology in terms of improved accuracy, response, interface with operator, ease of adjustment of range and span. This was made possible with use of digital circuits, microcontrollers, ADC, DAC. Today we hear about not only Smart Transmitter/Instruments, but Smart Control Valves, Smart Machines like Microwave Ovens, Washing Machines etc. Digital Oscilloscope also can be categorized as Smart Oscilloscope.

This is the Simple Smart DC fan Circuit Diagram. In almost all flats the elevators (lifts) are essential. In high rise buildings there are 2 or 3 or even more lifts. These lifts are major source of electrical energy consumption. Why? The lifts remain idle for most of the time and it is used during peak hours only like in morning from 6 am to 10 am and in evening from 5 pm to 9 pm. So out of 24 hours a lift is used mostly for 8 – 10 hours. Now the problem is, in a lift there is always a fan and a light that stays on continuously. Even if lift is not in used for longer period of time. Although the ON/OFF switches for fan and light are already given, no body turns it OFF. So the fan and light inside the lift stays ON continuously and makes complete waste of electrical energy. Such a waste of valuable electrical energy in this era is not at all desirable. Today all most all the countries are putting their strong efforts to save maximum electrical energy by all means. In India there is heav...
