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.

The project aims to construct an electronic device that can automatically detect water level with high precision and control the water supply. It will automatically shut off the water when the reservoir is full. The circuit uses an ultrasonic sensor to detect the water level and a microcontroller to control a transistor that switches the water pump on and off. When the water level reaches the sensor, the circuit signals an alarm and shuts off the pump. The water level indicator has applications for monitoring water levels in places like hotels, factories, homes, and commercial buildings to prevent water wastage and shortages.

Psa(group 3)
This document summarizes a student presentation about designing an automatic water pump switch using a microcontroller. The system uses sensors to detect the water level in a tank. When the level goes down, the pump turns on automatically. When the tank is full, the pump turns off to prevent wasting water. The project aims to efficiently manage water resources and electricity. An Arduino microcontroller is used to control a relay that switches the pump on and off based on the sensor readings. Circuit diagrams and code are presented, and it is concluded that the system works satisfactorily according to specifications.
Science fair presentation.pdf
This document summarizes a student science fair project to build an electronic soil moisture sensor using a simple circuit. The circuit uses probes inserted in soil to measure electrical resistance, which indicates how wet or dry the soil is. If the soil is dry, a LED will light up, and if the soil is wet, the LED will stay off. The students hypothesized this circuit could help determine if plants need watering. They assembled the circuit using common electronic components, tested it, and experimented with monitoring plant moisture levels and watering based on the sensor readings. The sensor worked but had limitations detecting moderate moisture levels. The students learned about simple circuits and using resistance measurements to gauge soil moisture.

Voltage doubler
A voltage doubler circuit uses a 555 timer IC connected in astable mode to generate a square wave input voltage. This input is fed to a voltage doubler block which uses diodes and resistors to multiply and output a voltage that is approximately twice the value of the input voltage. The document provides an address, abstract, block diagram, and lists components required for the voltage doubler circuit.
Over voltage abstract
This document proposes a low voltage and high voltage tripping mechanism to protect electronic devices from power supply damage. It uses two 555 timers as a window comparator to detect if the input voltage falls below or rises above a set value. If detected, a relay will cutoff the load for safety. The concept could be expanded to include an alarm and SMS alerts to notify users of voltage fluctuations.
Letter box abstract
The document describes an electronic letter box circuit that uses a 555 timer IC to detect when a letter is placed inside. When the letter blocks the light falling on an LDR, the LDR resistance increases, lowering the voltage to pin 2 of the 555 IC below 1/3 of the supply voltage. This causes the 555 output at pin 3 to go high, lighting an LED to indicate a letter is present. The circuit uses an LDR, LED, 555 timer IC, and battery to provide a low-power way to detect when something is placed in the letter box blocking the light to the LDR.

3.automatic street light abstract
This document describes a circuit that uses a light dependent resistor (LDR) sensor and comparator circuit to automatically turn street lights on at night and off in the morning. The circuit uses the output from the LDR sensor, which detects light levels, and a comparator to control a relay that switches the street lights on and off. It can also be used to automatically control electrical appliances in households based on light levels. Block and circuit diagrams are provided to illustrate how the system works along with a list of required hardware components.
2.pir based abstract
This project uses a PIR sensor to detect human presence in a locked home. When the PIR sensor identifies a human, it will trigger a comparator whose output activates a relay that causes a buzzer to ring, alerting occupants to the intrusion. The system includes a power supply, PIR sensor, LM324 comparator, 6V relay, and buzzer.
Embedded c program and programming structure for beginners
Embedded C programming is used to program microcontrollers that are found in many electronic devices. It involves writing code in the C language to control the functioning of embedded systems. Some key aspects of embedded C include using data types like char, int and float to store values in memory, keywords to perform specific tasks, and special function registers to access peripherals like ports and timers. The structure of an embedded C program typically involves comments, preprocessor directives, functions, variables and statements to read inputs, perform operations and output results.

Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Water level indicator abstract
- 1. Fotronichs, #102 ginnumudaliar street virupackchipuram, vellore-632002,ph:9791899533 ABSTRACT Water tank overflow is a common problem which leads to the wastage of water. Though there are many solutions to it like ball valves which automatically stop the water flow once the tank gets full. But being electronics enthusiastic wouldn’t you like an electronic solution for it? So here is a simple and handy DIY that will guide you to make a 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 4 levels (low, medium, high and full), we can create alarms for more levels. We have added 3 LEDs to indicate initial three levels (A, B, C), and one Buzzer to indicate FULL level (D). When tanks gets filled completely we get beep sound from Buzzer.
