WATER LEVEL INDICATOR
DESCRIPTION
Nowadays everybody has overhead tank at their homes, but the one who has a water tank above knows the kind of problems that they face. Water tank overflow is a common problem which leads to the wastage of water. Being electronics enthusiastic made a simple and handy circuit which will detect the water level and will raise an alarm upon getting the water tank full or a preset level.
This simple transistor based water level indicator circuit is very useful to indicate the water levels in a tank. Whenever tank gets filled, we get alerts on particular levels. Here we have created levels by alarms & we have added LEDs to indicate the level of water and one buzzer to indicate full level. When tanks gets filled completely we get beep sound from buzzer. So now we do not have to worry about overflow and water out anymore.

Presentation on knock door bell project by namit
This project presents a doorbell that alerts users when someone knocks on the door by playing a ringtone and illuminating an LED, without requiring wiring or drilling holes. The device uses a piezoelectric vibration sensor mounted on the door to detect knocks and convert the vibrations into an electrical signal. The signal is amplified and fed into a comparator circuit using an LM358 integrated circuit, with the sensitivity controlled by a potentiometer. When a knock exceeds the threshold, the comparator output triggers a buzzer to sound and notify the user of the knock. The device is powered by batteries and easier to install than a traditional doorbell.
Fire alarm
The document describes a simple fire detection circuit using a thermistor. The circuit uses a potential divider configuration with a thermistor and resistor to sense temperature changes. When the temperature and thermistor resistance rises due to heat, the voltage drop across the resistor increases, turning on a transistor and activating a buzzer alert. This simple, low-cost circuit can be used for fire detection in homes, schools, industries, and research facilities.
Voltage regulators
Voltage regulators are used to provide a stable DC voltage and can be classified as linear/series regulators or switching regulators. Series regulators work by using a transistor in series with the load to maintain a constant voltage drop. They are simple but inefficient. Switching regulators rapidly switch a transistor to transform voltage efficiently with less heat but are more complex. Integrated circuit voltage regulators like the 78XX series provide fixed voltages like 5V from an input voltage. The 723 regulator is adjustable and can provide higher output voltages than fixed regulators.

Simple Touch Alarm
BRIEF DESCRIPTION:
This simple touch sensitive alarm is developed by using NE-555 timer IC, operated as a monostable vibrator.
This touch alarm circuit will sound when somebody touches the trigger plate. Touch the sensing plate of the alarm with your finger and it starts beeping and then stops.
Touching it again and it goes again!
Here the stable stage is low, so the timer outputs low after the trigger is removed. Basically the circuit has a led which turns on when we touch a pin of timer. The led will be on for the time during which the trigger is present. Once the trigger is removed the led turns off.
This is a little and flexible circuit consists of a touch sensor and a NE-555 IC with a small buzzer as the output load. Two touch sensor strips of metal are mounted side by side & connected to the input of the circuit.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

Presentation knock door bell project by namit
- 1. PRESENTATION ON PROJECT KNOCK KNOCK DOOR BELL By :- Er.NAMIT SOOD
- 2. Objective The objective of this project is to build a device with a vibration to electrical transducer that alerts the user when somebody is at the door. Unlike a traditional doorbell, this doorbell plays a ring-tone when somebody knocks at the door. It also illuminates an LED to alert the user. It is easier to install than a traditional doorbell because no holes need to be drilled and no wiring needs to be done. The user simply installs batteries and mounts the device on their door.
- 3. Description of project In this modern world everyone wants something new, something different, so instead of using switch to ring the door bell just an alarm is produced by knocking the door which people feel more luxurious. The circuit of automatic alarm on knocking uses a thin piezoelectric plate, senses the vibration generated on knocking a surface (such as a door) to activate the alarm and can also be used to safeguard motor vehicles. The piezoelectric plate is used as the sensor. It consist IC LM358 to which speaker is connected at the output. Piezoelectric material is used at the input in order to convert any mechanical vibration into electrical variation, it avoids false triggering. The plate can be fixed on a door, cash box, cupboard, etc using adhesive. A 1-1.5m long, shielded wire is connected between the sensor plate and the input of the circuit. The circuit operates off a 9V or a12V battery.
- 4. Circuit diagram of project
- 5. Working of project The piezo drives a load resistor of 1M in parallel with a 5.1v Zener diode just to protect the IC's against any large voltage spikes in the event of a large physical bump. I found the raw output of the piezo unsuitable for direct input to the Arduino as it is typically a very small voltage signal and needs amplification, so I amplify the signal from the piezo with a 221 gain non-inverting op-amp using one side of an LM358. I use the other side of the LM358 for a comparator. The sensitivity of the vibration sensor is controlled using a potentiometer for the threshold (negative) input into the comparator. The other (positive) input to the comparator comes from the amplifier of the piezo signal. The output of the comparator provides a direct input to Arduino Uno digital pin 8. To hear when it senses vibration I use a simple piezo buzzer driven directly from Arduino Uno pin 13.
- 6. Simulation and program used using arduino
- 7. Conclusion Whenever a mechanical input is given as the input for piezoelectric material those variations converted into electrical variations and when it is interfaced with a circuit which amplifies, rectifies, filters those signals and buzzer is produced.
- 8. Future scope 1. Can be used as protective shield to the locker to avoid the robbery. 2. Can be used as door bells
- 10. Thank you
