Rainwater Harvesting
What is rainwater harvesting and why is it Important?
Water is our most precious natural resource and something that most of us take for granted. We are now increasingly becoming aware of the importance of water to our survival and its limited supply, especially in such a dry continent as Australia.

The harvesting of rainwater simply involves the collection of water from surfaces on which rain falls, and subsequently storing this water for later use. Normally water is collected from the roofs of buildings and stored in ....etc

Here is a simple rain alarm circuit that produces an audible alarm when ever rain falls. The rain detector circuit is based on two transistors (Q1 & Q2) and a NE555IC (IC1). The two transistors are wired as a switch which goes on when the base of Q1 is shorted to the positive of the supply by the rainwater falling on the sensor. When the transistors are ON power supply is available to the IC1 which is wired as an astable multivibrator. The output of IC1 drives the speaker to produce an alarm.

Water is basic need in every one s life. Saving and proper usage of water is very important. Here is an easy project which will give the alarm when there is rain, so that we can make some actions and save the rain water. As a result, we can increase the water levels of underground water by using underwater recharge technique. Rain water detector will detect the rain and make an alert; rain water detector is used in the irrigation field, home automation, communication, automobiles etc. Here is the simple and reliable circuit of rain water detec ....etc

BOILER CONTROL SYSTEMS
TYPES OF CONTROLS:
Control systems may be pneumatic, analog, digital, or a
combination of the three.The present industry standard is for a
distributed control system (DCS), a programmable logic controller (PLC), or a direct
digital controller (DDC). These work based on the information gathered from sensors.

CONTROL SELECTION:
-Microprocessor digital type of controls (e.g. PLC, DDC, or DCS) are used where a large number of control loops are involved.
-Pneumatic control devices should be us ....etc
