Smart Load Control system. A balanced power management system that saves unnecessary power those are not useful to us. For example running a fan with full speed at a normal temperature, keeping the full brightness of the room lights in…

Here’s the block diagram of our Microcontroller Based Integration of Renewable Energy system. We can clearly describe the working process through this block diagram. Firstly we have two energy sources to supply electricity. One is the Solar and the other…

GSM based Smart Home Automation is a very effective project for load monitoring & controlling. It has a smart intelligence system to monitor load status & temperature status. Based on the environment it can take various logical decisions. For example,…

Nowadays advertisement is going digital. Previously notices are showed using a paper stick to the notice board with glues, and it’s annoying to remove and attach notice with glue.  But now with the advanced technology, we can now show notice…

A fan regulator regulates the power of a fan that controls its speed. Previously regulators are made with an inductor which drops the input voltage of the fan and causes the fan speed down. Nowadays regulators are making electronically. The…

A solar charge controller regulates the voltage and current coming from your solar panels which is placed between a solar panel and a battery.It is used to maintain the proper charging voltage on the batteries. As the input voltage from…

This pump control system is based on GSM network technology for transmission of SMS from sender to receiver. SMS sending and receiving is used for ubiquitous access of appliances and allowing breach control at home. The system proposes two sub-systems.…

RFID is Radio Frequency Identification. An RFID reader is used to read RFID tags (which contain certain unique data stored in a chip). An RFID reader and an RFID tag, both have a coil surrounding them.  When an RFID tag…

A rain sensor or rain switch is a switching device activated by rainfall. There are two main applications for rain sensors. The first is a water conservation device connected to an automatic irrigation system that causes the system to shut down in the event of rainfall. The second…

This system DC motor Controller by Android is developed to control the speed of the DC motor in both clockwise and anticlockwise direction. For this DC motor is interfaced to the Arduino. A Bluetooth modem is used to receive direction…
