The main scheme is to develop an Arduino-based system that provides a complete home security system by alarming against unwanted things and notifying via SMS through mobile services when we stay out of the home. The main objective of this system is to provide a security system with Arduino programming that provides security against any unwanted situation and alert people by sending SMS messages.

- Water Level Indicator & Alarm
- Water level Indicator with LED
- Water Level Alarm
- Water Level Alarm Circuit using Level Sensor
- Summary
The level indicator monitors the water level of the circuit diagram tank and switches to the water pumps even after the water tank level drops. The tank water level is indicated using 5 LEDs and the water pump shuts off completely when the tank water level is full. The figure below shows the circuit diagram of the water level indicator which has 4 probes that are placed in the upper tanks and interfaces with port 2 of the microcontroller.
The electronic water level alarm is connected to the circuit alarm and is placed in the electronic water level circuit above it, which has the ability to alert a home. In this circuit, this circuit uses a liquid level sensor to measure the water level of the water tank. The water level indicator shows the water level and the top tank or other water container.
The tank water level shows the use of 5 LEDs and the water pump shuts off completely when the tank water level is full. The water level indicator consists of 4 probes which are placed in the upper tanks and interfaced with port 2 microcontrollers.

- Architecture of PIC16F73 Microcontroller
- PIC16F73 Microcontroller Pin Configuration
- Construction Details
- Memory Organization
Program and data memory can be accessed at the same time, so separate busses and details in this section. Additional information about device memory settings can be found in the Mid-range PIC Microcontroller Reference Manual (DS33023).

- Working Principal
This allows the programmer to emulate the program before downloading it to an IC (Integrated Circuit) microcontroller. Each flowchart 'box' has a purpose and replaces multiple lines of text programming code. A USB socket connects the computer to the programmable circuits, which allows the transfer of the program to the PIC microcontroller IC.

Finally, the threshold voltage became slightly greater than (+10V). The comparative output then goes high, forcing RS to set the flip-flop. An exponential growth capacitor appears across C and the output appears in a positive running pulse.

In general, there are two main limitations for the wireless system designer: it works at a certain distance and must transmit a certain amount of data at the data rate. We can connect directly to the controller 3 pin RF module; No encoder and decoder is needed. From the circuit, the power supply is connected to the 5V 28 microcontroller pin and the ground is connected to the 20th pin.
Here we have two switches that are well stretched to 5V with a microcontroller and these two switches form the input command of the microcontroller. We have an arrangement for a computer keyboard to connect regularly from the keyboard output to the microcontroller's input and from the Page 17 . At the receiver end we have +5V as the microcontroller has similar connections for the power supply.
We are using Pin 3.0 to connect RF module data pin and RF module pins 1 and 2 to GND and VCC. Data is decoded when received by the receiver module and the receiver pin is programmed to 10 microcontroller. Compared with other radio frequency devices, the performance of the RF module will increase the power of the transmitter; depending on many services such as the distance of a larger contact will be collected.
However, due to the high electrical power dissipation on the transmitter device, the battery-powered device may cause a short life. During this charging process, a charging current changes, (i) the electric charge equal to the rate of the plate flowing into the capacitor in opposition to any change in the voltage. There are a variety of diodes before the common PN junction diode, even though the basics are more or less the same.
Therefore, a specific diagram of the diode can convert AC to DC Pulsing Dc and this is sometimes also known as Rectifier. In general, the NPN transistor is the most commonly used bipolar transistor because the electron mobility is more than the hole dynamics. LCDs (liquid crystal displays) are used in all electronics projects to show the status of the process.

By controlling the automatic water level, the pump guarantees no overflow or dry running. The automatic water level control gives you the flexibility to determine the water level for the Pump Sum activity yourself. Automatic water level controllers are used in hotels, factories, residential apartments, commercial complexes, drainage, etc.
Automated water level controller automatically starts the pump volume as soon as the water level falls below the previously set level (usually 1/2 tank), the sooner the pumps will be turned off as soon as the pans are set.

We can also use this system to automate the electrical appliance control automation system by making some additional changes. The system specification shows the description of the function and performance of the system and the user. The scope of our project design and construction of a GSM and laser based control system for home applications is enormous.
The future implementation of the project is very high considering the amount of time and resources it saves. The project we have undertaken can be used as a reference or as a basis for realizing a scheme to be implemented in another higher level project, such as temperature update, device synchronization, home automation etc.
