The board has only one  relay driven by TTL circuit and MCT2E IC for isolation purpose.The board works on 12V but the input signal can come directly from microcontroller output working at 5V to control relays. Relay can switch varierty of AC or DC high voltage, high current 20A,loads working at 110V or 230V AC mains like lights, fans, motors and such. The status of relay is indicated by individual LEDs.

Controlling appliances is a main part of automation. The main object  of  Home  automation  is  to  provide  a  wireless communication  link  of  home  appliances  to  the  remote  user. The  main  objective  of  this  work  is  to  make  such  a  system which  controls  the  home  appliances  remotely.  Here we have demonstrated a simple yet a sophisticated way to control home appliances via an Android phone.

The components of solar powered intelligent drip irrigation system are shown in Fig. Soil moisture sensor is used for real-time collection of crop root soil moisture content and converting it into a signal in the range of Voltage V; and the signal will transformed as knowledge of water requirement of crop. Soil moisture content at the root zone of different crops is collected by using the soil moisture sensor. The threshold limit for the water requirement for a particular crop has been feed to system which in turn controls the operation the control system. The power needed for the operation of the control system has been met with the use of a solar panel and the display will receive the control signal and display the data stored using the sensor from the field.

Pull-up resistors are used in electronic logic circuits to ensure that inputs to logic systems settle at expected logic levels, if external devices are disconnected or high-impedance is introduced. They may also be used at the interface between two different types of logic devices, possibly operating at different power supply voltages.A pull-up resistor weakly "pulls" the voltage of the wire it is connected to towards its voltage source level when the other components on the line are inactive.

The Intelligent Vehicle Static Grounding System ensures safe loading and unloading of flammable and explosive material tank trucks by dissipating static electricity. The static charge accumulated on the vehicle body that can ignite a spark that results in fire or explosion. System gives green signal / enables relay to load or unload only after discharging stored static energy.
